In the figure below, if C is the center of the circle and 30 < C < 60, then which of the following expresses all possible values of a?

Select one:

A. 50
B. 60 < a < 70

C. 60 < a < 75

D. 75 < a < 90

E. 100 < a < 115

Option C.

Step-by-step explanation:

In the given figure C is the center of the circle.  

Let A and B are two points on the circle, such that

Since CA and CB are radius of the circle, therefore ABC is an isosceles triangle.

Using angle sum property,

Divide both sides by 2.

It is given that

    (Subtract from 180)

     (Divide by 2)

Hence, the correct option is C.

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
