Question

In right triangle PQR, the length of side P Q is 70, the measure of angle P is 90 degrees, and the measure of angle R is 38 degrees. How we will represents the length of side QR?

Answer 1

Answer:

70/sin38°

Step-by-step explanation:

According to question,we have

PQ=70 ,  ∠P=90° & ∠R=38°

We know, sine rule

So, Sin90° / QR = Sin38° / 70

on solving, we get

QR = 70 / Sin38°
