Question

Triangle PQR is similar to triangle STU, where P, Q, and R correspond to S, T, and U,

respectively. In triangle PQR, the length of PQ is 2 and the length of QR is 8. In triangle STU,
the length of ST is 9. What is the length of TU?
9
11
18
36

Answer 1

TU=36

Explanation:

use the side lengths of PQR to determine the proportionality of the two triangles. 9/2=4.5 so, multiply 8 by 4.5 to find TU.
