Answer:
72 degrees
Step-by-step explanation:
Slope
y=-(7/8)x+105
plug in 72 for the y
72=-(7/8)x+105
-177=-(7/8)x
72 = x
Answer: She has a $-7.50 balance
Step-by-step explanation: A = 3*12.5
A= 37.5
37.5-30= -7.5
Answer:
The ramp should be 32.9 feet longer.
Step-by-step explanation:
When the ramp is at 
to the ground, its length can be determined by applying the appropriate trigonometric function. Let the length be represented by l, so that;
Sin θ = 
Sin = 
l = 
= 
= 33.0048
l = 33.0 feet
When the angle is reduced to 
, the length of the ramp would be;
Sin θ =
Sin =
l = 
= 
= 65.9152
l = 65.9 feet
Change in length of ramp = 65.9 - 33.0
= 32.9
The ramp should be 32.9 feet longer.
