If you separate the triangles, you'll notice that both are literally the same triangle because all angles are the same.
S = r·α is the formula to find the arc length (s), given the radius (r), and angle measure (α) in radians.
If the angle measure is NOT given in radians you must convert to radians.
s = 8 · 2.6
s = 20.8 in
The answer is X=23 and y=9
The answer will be A. Hope it help!
