I think the answer 100,000
A straight line is 180° so....
9x+24 +6x - 24 = 180
15x=180. ( because you have to combine like terms.
X= 12
What exactly are you asking. Are you asking for area or perimeter?
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
