Check the picture below.
so, if we add all the arcs provided, we have a total of 153° + 60° + 53°, which gives us 270°.
keeping in mind that a circle has a total of 360°, the shaded region has to be a sum of 360° - 270°, or 90°.
now, notice the tickmarks on those angles in the graph above, meaning those two angles are twins, and 90°/2 is 45°, so each of those twins is 45°.
arcYW = 60° + 45°.

Answer:
A
Step-by-step explanation:
Its a right angle, so you have to use trigonometry.
To find x , you use sin60° = opposite/hypotenuse
opposite = x and hypotenuse = 5 . So,
sin60°= x/ 5
5sin60° = x
put the value into your calculator you ' ll get:
To find y, cos60°= adjacent/hypotenuse
adjacent= y and hypotenuse = 5. So,
cos60°= y/5
5cos60°=y
