Answer:
Your solution is 4.
Step-by-step explanation:
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc ⇒ x = 40/2 = 20°
Angle A = 100 , Angle C = 100 , Angle D =80
The circumference is usually three times as much as the diameter
<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
hope this helps :)
