Answer:
r = -5
Step-by-step explanation:
-11 = 1+3r+3
-11 = 3r + 4
3r = -15
r = -5
t = 2/3. Multiply the numbers in the parentheses by -1. It becomes 9t + -3t + -3 = 1. Combine like terms to get 6t + -3 = 1. Add 3 to both sides to get 6t = 4. Divide both sides by 6. t = 2/3
Just divide the arc the inscribe angle forms by 2. So 100/2 = 50 = a, and b is 55.
Positive: 690
Negative: -30
