just solve for inner angles which have to equal 180. Then use supplementary angles to get outer.
Answer:
70.3 ft
Step-by-step explanation:
The ratio of the adjacent side (33 or KM) to the hypotenuse (X or KL) is the cosine of the angle:
cos(62°) = 33/KL
Multiplying by KL/cos(62°) gives ...
KL = 33/cos(62°) ≈ 33/0.4694 ≈ 70.292 ≈ 70.3
The length of KL is about 70.3 feet.
