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°
Answer:
-2
Step-by-step explanation:
y = 3x + 2.5
x = -1.5
y = 3 x -1.5 + 2.5
= -4.5 + 2.5
= -2
Answer:
79
Step-by-step explanation:
1 container----------->14 seedlings
x containers-------------> 1113 seedlings
14x=1113×1
x=1113/14
x=79
