An exterior angle of thetriangle is 110 One of the opposite interior angle is 50. What are the twoangle |
|
Answer» We know that the SUM of In the DIAGRAM, PQR is a Triangle. ∴ ∠a + 110° = 180° ❪Linear pair❫ ⇒ ∠a = 180° - 110° ⇒ ∠a = 70° Hence, ∠a = 70°. ∴ ∠P + ∠Q + ∠R = 180° ❪Sum of ∠s of a Triangle = 180°❫ ⇒ ∠P + 30° + ∠a = 180° ⇒ ∠P + 30° + 70° = 180° ⇒ ∠P + 100° = 180° ⇒ ∠P = 180° - 100° ⇒ ∠P = 80° Hence, ∠P = 80°. Therefore, the other two ANGLES of the triangle are 70° and 80°. Hope it helps ツStep-by-step explanation: if it helps you mark it as brainliest |
