If ABC PQR, and C = 80°, A = 10°, then what will be the measure of Q?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 90°.
According to the given question,
ABC PQR, then
A = P, B = Q and C = R
In triangle ABC, A + B + C = 180°
⇒ 10° + B + 80° = 180°
⇒ B = 180° - 90°
⇒ B = 90°
So, Q = B = 90°
