The graphic says find BC and it says BC = 33 feet
Anyway, assuming the ladder is 34 feet, and makes an 82 degree angle,
cosine 82 degrees = adjacent / hypotenuse
adjacent = cosine 82 degrees * hypotenuse
adjacent = 0.13917 * 34
adjacent (or side BC) =

4.73178

feet
height (line AB) = sine (82 degrees) * hypotenuse (34 feet)
height (line AB) = 0.99027 * 34
height (line AB) = 33.67 feet
If the bottom side is ab then bc is <span>8.18535277, which to the nearest tenth is 8.2

The Angela's solution is wrong cause when you multiply you get a different answer.

alright give us a second
Answer:
you determine net force of an object by using this formula:
F=M×A or force=mass×acceleration
really hope this helps:)
|a| = -a if a < 0
The absolute value and the opposite of rational number is equal when a number is negative.
Examples:
|-7| = - (-7) = 7
|-0.5| = - (-0.5) = 0.5
