Answer:
3.24 feet
Step-by-step explanation:
A 17 -ft ladder leans against a building so that the angle between the ground and the ladder is 79 . Find the distance between the building and the ladder
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = x feet
Hypotenuse = 17 ft
The angle = 79°
Hence,
cos 79 = x/17
Cross Multiply
x = cos 79 × 17
x = 3.2437529214.feet
Approximately = 3.24 feet
Therefore, the distance between the ladder and the building = 3.24 feet
