In a triangle PQR, ∠P + ∠Q = 84°. Find the value of ∠R.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 96°.
∠P + ∠Q = 84°
The sum of the angles in any triangle is always 180°.
So, ∠P + ∠Q + ∠R = 180°
⇒ 84° + ∠R = 180°
⇒ ∠R = 180° - 84° = 96°
Therefore, the value of ∠R is 96°.
