Answer:

114.4 feet

Explanation:

In ΔNOP, the measure of ∠P=90°, the measure of ∠N=39°, and PN = 72 feet. Find the length of OP to the nearest tenth of a foot.

We solve using Sine rule

= OP/sin P = PN/ sin N

= OP/ sin 90 = 72/sin 39

Cross Multiply

OP × sin 39 = sin 90 × 72

OP = sin 90 × 72/sin 39

OP = 114.41 feet

Approximately = 114.4 feet
