Question

Construct a triangle PQ are in which angle Q is 45° angle R is 60° and QR is 6.5 cm
Answer for class 7 NCERT

Answer 1

Answer:

∆ PQR is the required triangle. On measuring ∠Q, it is 75°

Verification : We know that sum of angles of a triangle is 180°

∴∠P + ∠Q + ∠R = 180°

⇒ 60° + ∠Q + 45° = 180°

⇒ ∠Q + 105° = 180°

⇒ ∠Q = 180° – 105° = 75°.
