1. The two triangles below are similar. Answer questions (a) and (b). a. Solve for x.
b. Solve for y

a) We get the value of x : x = 9

b) We get the value of y : y = 4

Step-by-step explanation:

If two triangles are similar, then their corresponding angles are congruent and  corresponding sides are in proportion.

a. Solve for x.

We can write:

because corresponding sides are in proportion.

Now solving to find value of x

Cross multiply

So, we get the value of x : x = 9

b. Solve for y.

We can write:

because corresponding sides are in proportion.

Now solving to find value of y

Cross multiply

So, we get the value of y : y = 4

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
