Question

The measures of two angles of a traiangal are 72'° & 58° find the measure of the third angle

Answer 1

As we know, sum of the all angles of triangle is equal to 180 degree
Therefore : 180 minus the sum of two sides equal to the third side.
180 - (72+58)=third angle
180-130= 50=third angle
Hope you like my answer please mark it as brianlist please.

Answer 2

Answer:Let the measure of the third angle be x
Now,
72°+58°+x=180°(Angle sum property of triangle)
130°+x=180°
x=180°-130°
=50°
Therefore, the measure of the third angle is 50°
