Question

PLEASE HELP MEEEE WITH THIS !!!!!

Answer 1

To find the length of the arc AB, we can use the following equation:

$a= \frac{1}{2} (y-x)$

where a is the exterior angle, y is the arc furthest from the angle, and x is the arc nearest to the angle.

We know the value of a, but now x or y. However, we do know that x = 360 - y. We can use this information to find x (arc AB):

$50 = \frac{1}{2} (y - (360 - y))$

$50 = \frac{1}{2} (2y - 360)$

$50 = y - 180$

y = 230

If y = 230, then AB = 360 - 230:

360 - 230 = 130

The correct answer is 130.
