A) 16/40 reduces to 2/5 so 2/5 is correct
b) theoretically you would get heads up 20/40 times which reduces to 1/2

Answer: 46 degrees
Explanation:
Angle PRS = 98 degrees
The two smaller pieces add up to this larger angle, so,
(anglePRQ) + (angleQRS) = angle PRS
(3x-8) + (2x+6) = 98
5x-2 = 98
5x = 98+2
5x = 100
x = 100/5
x = 20
Then we can find each angle
- angle PRQ = 3x-8 = 3*20-8 = 52 degrees
- angle QRS = 2x+6 = 2*20+6 = 46 degrees
Notice how 52+46 = 98 to confirm the answers.
