In the figure below, triangle ABC is similar to triangle PQR, as shown below. What is the length of side PQ? (1 point)
a-33
b-34
c-35
d-36

36

Step-by-step explanation:

As you can see, side AB is similar with side PQ.

Also, side BC is similar with side QR.

If you divide the length of side QR (34.5) by the length of side BC (11.5)

you get 3.

3 is the ratio that you will use to find the other side. The ratio of triangle ABC to  PQR is 1:3

Multiply the side of AB (12) by 3 and you will get 36.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

the answer is 13 cm
