In AABC AB = 3x - 2, BC=x+4, and AC = 7. Also AB = BC Which term does NOT describe AABC?

Equilateral
Acute
Isosceles
Obtuse

Answers

Answer:

acute  maybe

Step-by-step explanation:

The given ΔABC is an equilateral triangle because all the sides are equal. The term which does not describe the ΔABC is obtuse option D is correct.

What is the triangle?

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

Given that:-

In AABC AB = 3x - 2, BC=x+4, and AC = 7. Also AB = BC

We know that AB = BC

3x - 2 = x + 4

3x = x + 4 + 2

3x = x + 6

2x = 6

x = 3

AB =  3x - 2 = 3(3) - 2 = 7

BC = x + 4 = 3 + 4 = 7

All three sides are equal so the triangle is an equilateral triangle. Hence given ΔABC is an equilateral triangle because all the sides are equal. The term which does not describe the ΔABC is obtuse option D is correct.

What point is the intersection of the graphs of the lines 2 x - y = 3
and x + y = 3?

Answers

Answer:

(2, 1 )

Step-by-step explanation:

Given the 2 equations

2x - y = 3 → (1)

x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by subtracting x from both sides

y = 3 - x → (3)

Substitute y = 3 - x into (1)

2x - (3 - x) = 3

2x - 3 + x = 3

3x - 3 = 3 ( add 3 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

substitute x = 2 into (3) for corresponding value of y

y = 3 - 2 = 1

Solution is (2, 1 )

A triangle has sides with lengths of 7 yards, 12 yards, and 13 yards. Is it a right triangle?​

Answers

Answer:

yh

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

We use the Pythagorean theorem.

a^2 + b^2 = c^2

7^2 + 12^2 = 49 + 144 = 193

13^2 = 169

Since 193 is not equal to 169, the triangle is not a right triangle.

A city planner is mapping out some new features for a triangular park. She sketches the park on grid paper. The coordinates of the vertices of the park are (1, 1), (1, 4), and (−3, 4).   The city planner wants to put a flower bed at the centroid of the park. What are the coordinates of the flower bed? (__,__)​

Answers

Answer:

The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

Step-by-step explanation:

To find the centroid of a triangle, use this rule centroid = ([tex]\frac{x1+x2+x3}{3},\frac{y1+y2+y3}{3}[/tex]), where (x1, y1), (x2, y2), (x3, y3) are the vertices of the triangle

∵ The vertices of the triangle are (1, 1), (1, 4), (-3, 4)

∴ x1 = 1 and y1 = 1

∴ x2 = 1 and y2 = 4

∴ x3 = -3 and y3 = 4

→ Substitute them in the rule above

∵ Centroid = ([tex]\frac{1+1+-3}{3},\frac{1+4+4}{3}[/tex])

∴ Centroid = ([tex]\frac{-1}{3},\frac{9}{3}[/tex])

∴ Centroid = ([tex]-\frac{1}{3}[/tex] , 3)

∴ The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

If Triangle ABC ≈ Triangle DBE, find the value of x.

Answers

Answer:

x = 49

Step-by-step explanation:

The sum of angles in a triangle add up to 180°.

∠CBA = ∠EBD (Vertically opposite angles are equal)

          = 52°

Since in the triangle DBE, you already know two of the angles, you can find ∠BDE which is equal to ∠CAB (x + 9)°.

∠BDE = 180° - 70° - 52°

          = 58°

∠BDE = ∠CAB

          = ∠(x + 9)°

          = 58°

x + 9 = 58

x = 58 - 9

x = 49

Hed never seen white people before, though his father sometimes traded skins and bows with the men. Little Bear had heard all of the warnings, but he still wanted to see what they looked like.2 One wagon fell behind the rest of the caravan. The rains of the past few days had turned the trail to thick mud, and the wagons oxen were tired. They made it another few minutes before Little Bear heard a loud crack, and the back corner of the wagon crashed to the ground.3 Two people from the wagon inspected the broken wheel. Little Bear froze when one pulled out a rifle and fired it into the air. He crouched into a small ball in the weeds, his heart drumming in his ears. But then he saw other people running to help the stranded travelers, and he knew that the rifle shot had just been a signal.4 Just then, there was a rustle in the grass beside Little Bear. He let out the long breath hed been holding when he saw it was just his older brother, White Deer, who silently signaled that they needed to return home before the settlers spotted them.5 Little Bear followed, but he paused a moment to glance back. Traveling out on the open prairie was dangerous, and the settlers were just people. He hoped the pioneer family got their wagon wheel fixed soon.Question: In paragraph 3, why does the author choose the words froze, crouched in a small ball and heart drumming in his ears?Group of answer choices-----------------------------------------------------------------------------------------------------------------------------Question: In paragraph 3, why does the author choose the words froze, crouched in a small ball and heart drumming in his ears?Group of answer choicesTo show that Little Bear was frightened by the sound of the rifle being shot.To show that Little Bear is cold.To show that Little Bear wanted to know more about the settlers.To show that Little Bear was afraid when White Dear crept up on him.-----------------------------------------------------------------------------------------------------------------------------Question: What is Little Bears attitude toward the white settlers in the last paragraph?Group of answer choicesLittle Bear is still scared of the settlers.Little Bear hopes they get their wheel fixed and leave soon.Little Bear wanted to know more about the settlers.Little Bear is no longer afraid of the settlers-----------------------------------------------------------------------------------------------------------------------------Question: Which statement from the text best supports Little Bears point of view about the white settlers at the end of the story?Group of answer choicesLittle Bear followed White Dear and returned home.He realized that the settlers were people just like him.Little Bear thought traveling on the open prairie was dangerous.Little Bear was relieved when he realized the rifle shot had just been a signal.-----------------------------------------------------------------------------------------------------------------------------Question: From what point of view is this story told?Group of answer choicesfirst personsecond personthird person limitedthird person omniscientThis ia all my points a drum full of rice weighs 241/6 kg.
