Question

Find Angle "A". please help me​

Answer 1

Step-by-step explanation:

<C = 180° - 150°

<C = 30°

<C = <B

<A + <B + <C = 180°

<A + 60° = 180°

<A = 120°

Answer 2

Angle ABC = angle ACB
Angle ACB = 180-150=30=angle ABC
ACB + ABC + CAB = 180
CAB = 180-(30+30)
CAB = 180-60=120
Angle “A” is 120 deg
