Question

solve it quickly........​

Answer 1

Given,

B = 90

C = 60

By angle sum property

A + B + C = 180

A.+ 90.+ 60 = 180

A. =. 180 - 150

A. =. 30

30 degree is the correct answer

Answer 2

Given :-

• Angle B = 90°
• Angle C = 60°

To Find :-

• Angle A

Solution :-

Angle B = 90°

Angle C = 60°

Let Angle A = 'x'

A.T.Q.

Angle A + Angle B + Angle C = 180° (Angle sum property of triangle)

Substituting the value :-

Angle x + 90° + 60° = 180°

Angle x + 150° = 180°

Angle x = 180° - 150°

=> Angle x = 30°

∴ Angle A = 30°
