Answer:
78.5°
Step-by-step explanation:
We solve for the above question, using the formula for the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = The distance between the house and the base of the ladder = 4 feet
Hypotenuse = Length of the Ladder = 20 feet
Hence,
cos θ = 4/20
θ = arc cos(4/20)
θ = 78.463040967°
Approximately = 78.5°
Therefore, the angle that the ladder makes with the ground is 78.5°
The length of the rectangle would be X2 - X1
The height of the rectangle would be Y2-Y1
Perimeter = 2 X length + 2 times height
The perimeter would be 2(X2-X1) + 2(Y2-Y1)
The first choice would be the correct answer.
