In a ΔABC, the sides AB and AC are extended to P and Q, respectively. The bisector of ∠PBC and ∠QCB intersect at a point R. If ∠R = 68°, then measure of ∠A is .
Answer & explanation
Correct answer: option 2
∠R = 90° - \(\frac{∠A}{2}\)
68° = 90° - \(\frac{∠A}{2}\)
\(\frac{∠A}{2}\) = 90° - 68° = 22°
∠A = 44°
