R^m ÷ r^n is equal to r^(m-n).
For example, 2^5 <span>÷ 2^3 = 2^2.

Answer:
The length of the ladder = 6.5077 ft
Step-by-step explanation:
Given A ladder leans against the side of a house
Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house
Let 'C' be the point of observation.
Given CA= 16 ft
From right angle triangle
x = 16 × cos 68°
x = 16 × 0.4067
x = 6.5077
x = 6.5 ft
The length of the ladder = 6.5 ft
When I do what the problem statement says, I get 47° for the left angle and 58° for the right one. They are not congruent.
