Question

in the given diagram find the value of x​

Answer 1

Answer:

i) → Let the angle A,B,C

A = 45° , B = 30° , C = X

→ A+B+C = 180°

→ 45°+30°+X = 180°

→ 75°+X = 180°

X = 180°-75°

X = 105°

Answer 2

ii)

→ Let the angle A, B,C

The corner angle is 90°

Now,

→ A = x°

→ B = 30°

→ C = 90°

Whole angle of a triangle = 180°

According To Question

→ A+B+C = 180°

x+30+90 = 180

x+120 = 180

x = 180-120

x = 60°

Angle of C = 60°
