So the probability of rolling a number greater than 2 is 4/6. So 4/6 times 150 should give you the answer 100.
We don't know whether those two sides are both legs
of the right triangle, or if BC is the hypotenuse.
If AC and BC are both legs, then
AB = √ (AC² + BC²)
= √ (7² + 8²)
= √ (49 + 64) = √ 113 .
If BC is the hypotenuse of the right triangle, then
AB = √ (BC² - AC²)
= √ (8² - 7²)
= √ (64 - 49) = √ 15 .
Answer: x=75
Explanation:
x+10+x+20=180
combine like terms
2x+30=180
subtract 30 from each side
2x=150
divide each side by 2
x=75
Sum of all interior angles of n-gon = ( n - 2) x 180.
Sum of all interior angles of 57-gon = (57 - 2) x 180 = 9900°
one angle = 9900 ÷ 57 = 173.68° (nearest hundredth)

Answer : One angle = 173.68°
