Find BC
(triangle)
Side = 34ft
bottom= 33ft
inside = 82 degrees
Hope the picture helps! I apologize for my handwriting, I tried to make the numbers more noticeable with pen.

Answer :

If the bottom side is ab then bc is 8.18535277, which to the nearest tenth is 8.2

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
