which triangle is similar to an equilateral triangle with side lengths of 5.2 cm

a. a right triangle with a perimeter of 15.6 cm
b. a equilateral triangle with a perimeter of 10 feet
c. any triangle with a perimeter of 15.6 cm
d. an isosceles triangle where two of the side are 5.2 cm

Answer:

x = 5

Step-by-step explanation:

27= 3 (3х - 6)

27 = 9x - 18

27 + 18 = 9x

45 = 9x

45/9 = x

5 = x

x = 5

Step-by-step explanation:

the difference of 2x and 15 is less than or equal to the

sum of 4x and 17

i.e.,

2x - 15 < 4x + 17

if you want to find ahead then

2x - 15 = 4x + 17

2x - 4x = 17 + 15

- 2x = 32

x = - 32/2

x = - 2

Answer:

[tex]\dfrac{5}{8}[/tex] butter was left after she was done baking.

Step-by-step explanation:

Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.

We need to find how much butter was left after she was done baking.

It can be calculated as follows,

Left =

[tex]=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}[/tex]

Hence, [tex]\dfrac{5}{8}[/tex] butter was left after she was done baking

Hey there!

The correct answer is adjacent.

The exact definition in the Oxford dictionary is "next to or adjoining something else."

Hope it helps and have a great day!

P.S. A picture of adjacent angles is below, you can see they are adjacent because they are connected.

Answer:

slope: -3; y-intercept: (0,15)

Step-by-step explanation:

The slope is -3, simply move 3x to the right side for slope intercept form, the y-intercept is where x =0 so set x equalt to zero. 3(0)+y=15, y=15

Answer:

65 degrees

Step-by-step explanation:

The missing angle on the bottom is 35 degrees. This is because it lies on a straight line with the other angle being 145 degrees and a straight line is always 180 degrees, so 180-145=35 degrees. Now we have to find x so we should add the two known angles (35+80=115) and subtract it from 180 (180-115) to get 65 degrees for x.

the common difference in the arithmetic sequence: 21, 15, 9, 3, -3, ... is 6

Answer:

[tex]\huge\boxed{\sf x = 8a}[/tex]

Step-by-step explanation:

[tex]\sf \frac{3}{a} x - 4 = 20\\\\Add \ 4 \ to \ both \ sides\\\\\frac{3}{a} x = 20+4\\\\\frac{3}{a} x = 24\\\\Multiply \ both \ sides \ by \ a\\\\3x = 24 * a\\\\Divide \ 3 \ to \ both \ sides\\\\x = 24a / 3\\\\x = 8a\\\\\rule[225]{225}{2}[/tex]

Answer:

[tex]y = \frac{1}{2}x^{2} - 3x + 11.5[/tex]

Step-by-step explanation:

Vertex Form of a quadratic equation;

[tex]y = a( x - h )^{2} + k[/tex]

Vertex of the parabolas (h, k)

The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;

[tex]y = a ( x + 3 ) ^{2} + 7[/tex]

Now substitute in the given point; ( -1, 9) and solve for a;

[tex]9 = a( (-1 ) + 3)^2 + 7\\9 = a (2)^{2} + 7\\9 = 4a + 7\\-7 -7\\2 = 4a\\\frac{1}{2} = a\\[/tex]

Hence the equation in vertex form is;

[tex]y = \frac{1}{2}(x - 3)^{2} + 7[/tex]

In standard form it is;

[tex]y = \frac{1}{2}x^{2} - 3x + 11.5[/tex]

Answer:

97

Step-by-step explanation:

you square 72 and 65 and add them together then take the square root of your answer aka 97 and thats the hypotenuse

Answer:

Step-by-step explanation:

Pythagorean theorem state that

Hypotenuse² = altitude² + base²

Pythagoras theorem states that square of hypotenuse of a right angled triangle is equal to the sum of squares of base and altitude of that triangle.

Hypotenuse² = Base² + Altitude ²

Hey there!

For equations like this I usually find the GCF or Factors of the given numbers for both of numbers and factor/solve it from there!

So, I’ll do the same thing for you.

[tex]\bf{4x: 1,2,4,\& \ x}\\ \bf{16: 1,2,4,8}}[/tex]

GCF: [tex]\bf{4}[/tex]

[tex]\boxed{\bf{Answer: 4(x - 4)}}\checkmark[/tex] (Just distribute and it’ll convert back to the equation in your question

Good luck on your assignment and enjoy your da!

Answer:

8×8×8 =512

Step-by-step explanation:

prove me wrong

Answer:

512 cm

(a) See the attached sketch. The jet makes a right triangle with the ground with hypotenuse y. Since the angle of depression is 56°, and the plane in which the jet is flying 300 m in the air is parallel with the ground, the angle of elevation in the right triangle is also 56°. Use the definition of sine to solve for y.

sin(56°) = (300 m)/y   →   y = (300 m)/sin(56°)

The uppermost angle in the blue triangle has measure equal to the difference between the two given angles of depression, 56° - 30° = 26°, and the rightmost angle is also 30° by the same reasoning as before. Then by the law of sines,

x/sin(26°) = y/sin(30°)   →   x = sin(26°)/sin(30°) y ≈ 317.2627 m

(b) No, the field is not long enough.
