Question

What is the value of b ???? a 54 b 120 c 30 d 60

Answer 1

Answer:

c. 30

Step-by-step explanation:

We have been an image of a circle. We are asked to find the value of b.

Upon looking at our given diagram we can see that angle 'b' is inscribed angle of our given circle and measure of intercepted arc is 60 degrees.

We know that measure of an inscribed angle is half the measure of its intercepted arc.

$m\angle b=\frac{60^{\circ}}{2}$

$m\angle b=30^{\circ}$

Therefore, the value of b is 30 and option 'c' is the correct choice.

Answer 2

<b = 60/2 = 30

answer
C. 30
