When solving two step equations you must solve one part of the equation so that you can solve the second part.
In one step equations you can just solve the equation as is.
Option B:
25 degrees
Solution:
Given data in triangle PQR,
The side opposite to angle P is p.
The side opposite to angle Q is q.
The side opposite to angle R is r.
q = 36, r = 20, angle Q = 50°.
<u>To find the measure of angle R:</u>
Using law of sine,


Take only two sides.

Substitute the given values.

Do cross multiplication.

sin 50° = 0.766





⇒ R = 25.18°
⇒ R = 25° (approximately)
Option B is the correct answer.
Hence the measure of angle R is 25 degrees.
