Answer:
37.74 ft
Explanation:
An angle and its opposite side are known
Sin (of the angle)= opposite/ hypotenuse
The hypotenuse is equal to the length of the ladder, therefore solve the hypotenuse
Sin (32)= 20/ hypotenuse
hypotenuse= 20/ Sin (32)
Sin (32)=0.5299
hypotenuse= 20/ 0.5299
37.74 ft
Hopefully this helps :)
