Question

PLEASE HELP!!!!! find the measure of the arc or central angle indicated. assume that lines which appear to be diameters are actual diameters.

Answer 1

275

Explanation:

The angle start in V then goes the left to Y and ends in W

First you add the First 34 degrees from V to U.

Then the 90 degrees from U to Y. (you can see it has a square on the angle therefore its 90).

After that you add another 36 degrees from Y to X.

Finally to get the unknown angle from X to W you subtract all the other angles from 360 degrees.

360-245=115

Then add all the angles and you get 275 degrees.

Might be wrong but I think its correct

Answer 2

B

Explanation:

Remark

If you started at W and went all the way around the circle until you wound up back at W, you will have gone 360 degrees. Since the angle measurement that prevents that is 85 degrees, the answer must be 360 - 85 = 275.
