Question

O is the center of the given circle. The measure of angle O is 128 degrees. Assuming that lines that appear to be tangent are tangent, what is the value of x.
At first I thought it was 52 but that doesn't really seem right to me.

Answer 1

The point at which the line is tangent with the circle. What angle will that form with the radius?

Answer 2

90 right?

Answer 3

It is 52 then isn't it.

Answer 4

Correct...If you bisect angle O. What will be the two angles?

Answer 5

Supplementary?

Answer 6

The angle is 128 degrees so if you bisect it the two angles will be?

Answer 7

Oh 64

Answer 8

So what will be the angle for the smaller angle

Answer 9

26

Answer 10

So what is the answer?

Answer 11

x=52

Answer 12

Good job
