Answer:
Ramp is 10.4 feet long.
Step-by-step explanation:
Ramp AC is is making an angle of 15 with the ground BC.
The end C of the ramp is 10 feet from the base B of the building.
We have to find the length of ramp.
Let x feet is the length of the ramp.
Now Cos15° =
0.9659 =
x =
x = 10.35 ≈ 10.4 feet
Therefore, ramp is 10.4 feet long.

Answer:
A) Quantity x minus 5 over quantity x plus 1, where x≠-1 and x≠-9
Step-by-step explanation:
Simplifying the numerator first:
x² + 4x - 45 using the quadratic formula you get;
(x - 5)(x + 9)
Then simplifying the denominator x² + 10x + 9 using a quadratic formula you get;
(x + 1)(x + 9)
Dividing the numerator and denominator now gives;
Cancelling (x + 9) throughout leaves you with;
The only restrictions here is if x = 1 and 9 which will give an undefined answer.
