#21 the answer is does √ 9^2 + 2^2
a^2 + b^2 = c^2
9^2 + 2^2 = c^2
√ 9^2 + 2^2 = √ c^2
Total number of marbles=5+3+4=12
Probability of picking a red marble =5/12
4.5(4-x) + 36 = 202 - 2.5(3x + 28)
Distributive property
18 - 4.5x + 36 = 202 - 7.5x - 70
Combine like terms
-4.5x + 54 = -7.5x + 132
Add 7.5x to both sides
3x = 78
Divide both sides by 3
x = 26
Answer:
50 degrees
Step-by-step explanation:
They are alternate exterior angles, so they add up to 180 degrees.
