Question

11. In AABC, ZA = 2C and B = LA + 2C. Find the measures of the angles of the triangle.
70. Find these multiples

Answer 1

Answer:

Correct option is

A

56

Given:-

∠B=76°

∠C=48°

∠A=?

As we know that, sum of all angles of a triangle is 180°.

∴∠A+∠B+∠C=180°

⇒∠A+76°+48°=180°

⇒∠A+124°=180°

⇒∠A=180°−124°

⇒∠A=56°
