In a ABC if _A = 72º and _B = 63. find_C
​

Answer 1

Answer:

$\huge\rm\pink{Answer:}$

In ABC,

Angle A = 72°

Angle B = 63°

Angle C = ?

By angle sum property ,

Sum of all angles of a triangle = 180°

Therefore,

A + B + C = 180

72 + 63 + C = 180

135 + C = 180

C = 180-135

C = 45°

Answer 2

Answer:

we know that,

A+B+C =180°

or,72°+63°+C =180°

or,135°+C =180°

or,C =180° -135°

or,C = 45°
