Question

In ΔRST, the measure of ∠T=90°, the measure of ∠S=75°, and ST = 64 feet. Find the length of TR to the nearest tenth of a foot.

Answer 1

362 feet

Explanation:

Answer 2

238.9 ft

Explanation:

R = 180 - 90 - 75 = 15

TR/sin(S) = ST/sin(R)

TR/sin(75) = 64/sin(15)

TR = sin(75) × 64/sin(15)

TR = 238.8512516844

Or,

tan(S) = TR/ST

TR = 64tan(75)

TR = 238.8512516844
