Exercise 35 Page 557

Start by identifying the corresponding vertices in the similar figures, then identify the pairs of congruent angles.

x=63, y=32

Practice makes perfect

We are told that the given figures are similar, and we want to find the values of x and y for the missing angle values. Let's analyze the given polygons.

Since we are given that A B C D ~ Q S R P, we can identify the pairs of congruent angles by matching them using the order they appear in the similarity statement.

ccccc A & B & C & D ↓ & ↓ & ↓ & ↓ Q & S & R & P Let's highlight the corresponding vertices and angles on the graph.

With this information, we can write two equations. One equation in terms of x and the other in terms of y. (x+34)°&= 97° (3y-13)°&= 83° Now we can use these relations to solve for the values of x and y. Let's start with x.
x+34=97
x=63
We will solve for y in a similar way.
3y-13=83

Solve for y
3y=96
y=32
