Answer:
56°
Step-by-step explanation:
The two marked angles are supplementary, so total 180°.
(2x +8) +(x -2) = 180
3x +6 = 180 . . . . . . . . . . collect terms
x + 2 = 60 . . . . . . . . . . . divide by 3
x = 58 . . . . . . . . . . . . . . subtract 2
∠DCB = x-2 = 58 -2
∠DCB = 56
Answer: The answer is 5
Step-by-step explanation: When using the pythagorean theorem, the 2 short sides are a and b, and the longest is c. Then you fill in the equation and solve.
Answer:
The height is 15 feet
Step-by-step explanation:
If you use the formula for cone height and substitute in your values:
h=3 x (V/πr^2)
h=3 x (81430.1/72^2π)
h=15
