As you can see those two angles are supplementary which the sum of two angles = 180°
So,
(9a + 6) + 75 = 180
Subtract 75 on both sides:
9a + 6 = 105
Subtract 6 on those sides:
9a = 99
Divide 9 on both sides:
a = 11

If I'm correct the answer is 30%. I think it is 30% because if you divide 27 by 90 it equals 0.3 which is 30%
Answer:
0.7499 miles per minute
Step-by-step explanation:
Google "what is 45 mph to minutes"
120/2 = x/5....120 miles to 2 hrs = x miles to 5 hrs
cross multiply
(2)(x) = (120)(5)
2x = 600
x = 600/2
x = 300....the motorcyclist would travel 300 miles in 5 hrs
or u could do it this way..
120/2 = 60 miles per hr
60 * 5 = 300 miles
Answer:
The area of shaded sector
Formula A = (θ / 360°) × πr²
θ=360°-140°=220°
r=18yd
We have A=(220/360)×3.14×(18)²
=621.72yd²
Area of sector is621.72yd².
