In δrst, the measure of ∠t=90°, the measure of ∠s=66°, and st = 2.2 feet. find the length of tr to the nearest tenth of a foot.

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle TRS

The tangent of angle ∠S is equal to divide the opposite side to angle ∠S (TR) by the adjacent side to angle ∠S (TS)

so

we have

substitute

solve for TR

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
