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

20/28 = 3x / (4x + 2)

84x = 20(4x + 2)
84x - 80x = 40
4x = 40
x = 10

so the 2 lines are equal to 30 and 42
