Question

In pqr the measure of r is 90 degrees the measure of q is 38 degrees and qr is 8.8 feet. Find the length of pq to the nearest tenth of a foot

Answer 1

11.2 feets

Explanation:

Angle, P = 180 - (38 + 90) = 52

Using trigonometry :

Length pq:

SinP = opposite / hypotenus

Sin52 = 8.8 / pq

0.7880107 * pq = 8.8

pq = 8.8 / 0.7880107

pq = 11.167361

Hence, length of pq = 11.2 feets
