Answer:

180 - 58 - 90 = 32

15/sin90 = PR/sin32

PR = 7.95

15^2 - 7.95^2 = sqrt(161.79)

PQ = 12.72

PQ = 12.72

Answer:


PQ=12.72

Explanation:

Given in the right angled triangle:

QR=15, ∠R=58°

sin (A°)=
(Perpendicular)/(Hypotenuse)


sin58°
=(PQ)/(QR)

Given: sin 58°≈0.848


0.848=(PQ)/(15)


PQ=0.848*15\\\\PQ=12.72

So, the measure of PQ is 12.72
