Question

1. The measures of two angles of a triangle are 72º and 58º. Find the measure of the third angle.​

Answer 1

Step-by-step explanation:

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 50o.

Answer 2

Answer:

50°

Explanation:

Let the third angle be x.

By Angle Sum Property of triangle :-

sum of all angles of triangle=180°

72°+58°+x= 180°

130°+x =180°

x= 180°-130°

x= 50°

so the third angle is 50°
