Question

One of the angles of triangle is 80and the other two angles are equal. Find the measure of each of the equal angles?

Answer 1

Step-by-step explanation:

Let the angles be x

By Angle sum property of triangle

x+x+80° = 180°

2x +80° = 180°

2x = 180° - 80°

2x = 100°

x = 100/2

x = 50°

Answer 2

Answer:

angle A=80

angle B =x

angle C=x

all angles of the triangle=180 degree

A+B+C=180

80+x+x=180

80+2x=180

2x=180-80

2x=100

x=100/2

x=50

angle B= 50

angle C= 50
