Question

If the measure of one angle of a triangle is 80 and the other two angles are equal in measure then find the measure of each equal angle of the triangle.​

Answer 1

Answer:

Sum of All angles of a triangle are supplementary= 180°

80+x+x=180°

80+2x=180

2x=180-80=100

x=100/2=50°

hence each angle is

50°

50°

80°

Answer 2

Step-by-step explanation:

Sum of the angles of a triangle = 180°

One angle = 80°

Remaining two angles are equal

let the the angles be= x and x

x+x+80° = 180°

2x+ 80°= 180°

2x= 180°- 80°

2x = 100°

x= 100÷ 2

x = 50°

one equal angle = 50°

another equal angle = 50°
