Given: tangent to circle o. if m c = 57°, then m bdr =

a 57
b 90
c 114

The correct option is A.

Step-by-step explanation:

Given information: O is the center of the circle, and measure of angle C is 57°.

Alternate segment theorem: According to the alternate segment theorem an angle between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.

Line RD is tangent to the circle at point D.

Using alternate interior theorem,

Therefore option A is correct.

the answer would be the last one (constat) she stays at the same rat every two mintues it goes up by 0.4
