Question

2 angels of a triangle are 72° and 63°. find the 3rd angle ​

Answer 1

Step-by-step explanation:

Given that:- Two angles are 72°,63°

To find :-third Angle.

Solution :- Let the third angle be x ,

then:- 72+63+x=180

x+135=180

x=180-135

hence x=45°.

Now, third angle =45°

hope it will help you Dear.

Answer 2

Answer:

In Triangle ABC

Angle A = 72°

Angle B = 63°

Angle C = ?

By using angle sum property,

Angle A+ Angle B+ Angle C = 180°

72°. + 63° + Angle 3 = 180°

135° + Angle C = 180°

Transposing 135° to RHS

Angle C = 180° - 135°

= 45°

Hence, the sum of the third angle of a the traingle ABC = 45°
