Right triangle = Pythagoras theorem.
a^2+b^2=c^2
there's already c and b so
10^2-8^2=a^2
100-64= 36
a^2=36
square root both sides
to get 6.

What is the perimeter of the parallelogram to the left?

zhuklara [117]

A parallelogram is a polygon that has opposite side parallel and congruent. If you already know that two of the side lengths is 8 cm and 9 cm, the other two sides will also be 8 cm and 9 cm because it has 2 pairs of congruent sides. 8+8+9+9=34 cm for the perimeter.

Write the coordinates for the given dilation

Olegator [25]

<u>Answer:</u>

D $_o$ of Y = (-3/2, -1)

<u>Step-by-step explanation:</u>

We are given three points on the graph:

X (4, 0)

Y (3, 2)

Z (2, 2)

and the scale factor of dilation which is $-\frac{1}{2}$ .

Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.

Y = $(-\frac{1}{2}$ × $3$ , (-\frac{1}{2}[/tex] × $2)$

Y = $(-\frac{3}{2} , -1)$
