Question

please find angle ABC please I will give you brainliest ​

Answer 1

Answer:

240°

Step-by-step explanation:

Given, ∠ADC = 120°

We know that, angle subtended at the centre by an arc is twice the angle subtended by it at the remaining part of circle.

∠ABC = 2∠ADC = 2 x 120° = 240°

Answer 2

Answer:

a+b+c=120*

so,= let all algebra be =x

so,=x+x+x=120*

=3x=120*

x=120*/3

therefore, x=40
