Question

if the measure of two angles of a triangle are 52 degree and 78 degree find the measure of the third angle

Answer 1

Sum of the 3 angles in a triangle is 180°

.

Find the third angle:

180 - 52 - 78 = 50°

.

Answer: The third angle is 50°

Answer 2

The sum of all 3 angles of a triangle should be 180°.
So lets consider the 3rd angle as x,
therefore,
52° + 78° + x = 180°
130° + x = 180°
therefore,
x = 180° - 130°
x = 50°.
hence, the third angle is 50°.
Hope this helps.
