Given:
[tex]\Delta ABC\sim \Delta QRS[/tex]
To find:
The missing value of m.
Solution:
We have,
[tex]\Delta ABC\sim \Delta QRS[/tex]
Corresponding parts of similar triangles are proportional.
[tex]\dfrac{AB}{QR}=\dfrac{AC}{QS}[/tex]
Putting the given values, we get
[tex]\dfrac{m}{10}=\dfrac{2}{4}[/tex]
[tex]\dfrac{m}{10}=\dfrac{1}{2}[/tex]
Multiply both sides by 10.
[tex]\dfrac{m}{10}\times 10=\dfrac{1}{2}\times 10[/tex]
[tex]m=5[/tex]
Therefore, the value of m is 5.

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? (__,__)
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)

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

Step 2: Evaluate
Substitute in y: (-2)²Exponents: 4What point is the intersection of the graphs of the lines 2 x - y = 3
and x + y = 3?
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?
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.
