Angle abc is inscribed in a circle as shown. what is the measure, in degrees, of angle abc?

Answer

Find out the measure, in degrees, of angle ABC .

To prove

The relationship between inscribed angles and their arcs

The measure of an inscribed angle is half the measure the intercepted arc.

The formula is  

As given in the diagram

The measure of the intercepted arc A to B is 120°.

Put value in the formula

∠ABC = 60°

Therefore the measure of the ∠ABC is 60° .

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
