Measure of angle m∠SQR = 70.9°
Given
m∠RSQ = 29.1°
m∠QRS = 80°
To find: m∠SQR = ?
Since, the sum of angles of a triangle is equal to 180°.
For ΔQRS, ................................ (Refer attached figure)
m∠RSQ + m∠QRS + m∠SQR = 180°
m∠SQR = 180 - (m∠RSQ + m∠QRS) = 180 - (80+29.1) = 180 - 109.1 = 70.9°
m∠SQR = 70.9°
