Question

two angles of a triangle are 72 degree and 63 degree. find the third angle​

Answer 1

Answer:

45 degrees

Step-by-step explanation:

Angle 1 = 72 degrees

Angle 2 = 63 degrees

Angle 3 = x

Angle 1 + Angle 2 + Angle 3 = 180 degrees (angle sum property of triangle)

72 + 63 + x = 180

135 + x = 180

x = 180 - 135

x = 45 degrees

Angle 3 = 45 degrees
