Question

One of the angles of a triangle is 130°, and the other two angles are equal. What is the measure of each of these equal angles?

Answer 1

Answer:

let X be the 2 equal angles of triangle

Sum of angles of a triangle is 180°

X+X+130°=180°

2X+130°=180°

2X=180°–130°

2X=50°

X=50°/2=25°

Measure of each angles are 130°,25°,25°
