A 20 foot extension ladder is placed in a wall making an angle of elevation for 85 degrees with the ground. If a person at the t
op of the ladder leaned back, rotating the ladder away from the wall, how far to the nearest foot would the person fall before hitting the ground?
1 answer:
Answer:
21.74 ft
Step-by-step explanation:
We use Cosine because we are dealing with the Adj and Hyp
Cos 85 = x/20
x = 20 Cos 85
x = 1.74 feet away from the base of the wall.
Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft

Answer:
d = -19
Step-by-step explanation:
64 = -3d + 7
Subtracting 7 on both sides,
64-7 = -3d
57 = -3d
Divide both sides by -3,
d = -19
Answer:
the answer is x= -3
y = -14
Answer:
yes, assuming you meant
x^3 + 5, it is a polynomial
Step-by-step explanation:
Answer:
slope: 3/2
y-intercept: 3
Step-by-step explanation:
This equation is in the form y=mx + b, where m=slope and b=y-intercept.
y = 3/2x + 3
m = 3/2 = slope
b = 3 = y-intercept
