Just need a little guidance on this question

OpenStudy (fruitcakeninja):

What is the question.

zarkam21 (zarkam21):

OpenStudy (agent0smith):

Since you're given the central angle (at the center of the circle), the measure of the arc is the same as the measure of the angle.

zarkam21 (zarkam21):

So would I add it

OpenStudy (agent0smith):

Read what I said again. " the measure of the arc is the same as the measure of the angle."

zarkam21 (zarkam21):

115

zarkam21 (zarkam21):

The angle in the picture is 115

OpenStudy (agent0smith):

Yes it is.

zarkam21 (zarkam21):

So that means the answer is 115

OpenStudy (agent0smith):

Yep

zarkam21 (zarkam21):

Would that mean this is 99 to

zarkam21 (zarkam21):

OpenStudy (agent0smith):

No. The measure of arc AB would be 99 degrees. AXB is the bigger arc. You know that there's 360 degrees in a circle, right?

zarkam21 (zarkam21):

Yes I know that

zarkam21 (zarkam21):

So would it be 360-99

OpenStudy (agent0smith):

Yep

zarkam21 (zarkam21):

So final answer is 261

zarkam21 (zarkam21):

?

OpenStudy (aaronandyson):

What's the radius of the circle?

zarkam21 (zarkam21):

99

OpenStudy (aaronandyson):

99 degree is the measurement of the arcAB i guess.

OpenStudy (agent0smith):

@zarkam21 yes. I shouldn't need to check that you did 360-99 correctly lol, it's not hard to check with a calculator
