Question

The measure of two angles of a triangle are72° and58° . find the measure of the third angle​

Answer 1

Answer:

The measures of two angles of a triangle are 72° and 58°. Let the third angle be x. Now, the sum of the measures of all the angles of a triangle is 180o. The measure of the third angle of the triangle is 50.

Answer 2

Answer:

sum of all angels of a triangle is 180°

let the third angle be x

therefore ,

72° + 58° + x = 180°

130° + x = 180°

x = 180° ― 130°

x = 50°
