If the mountain is 1,200 feet tall, find the length of the ski lift. * 360 ft
452 it
Ski Lint
Mountain

The length of the sky lift is 3.387.05 ft

Step-by-step explanation:

By an online search, i  found that the sky lift rises at an angle of 20.75 degrees.

Then we can think on a triangle rectangle, such that:

One cathetus is 1200ft, this is the opposite cathetus to the angle of 20.75°

The length of the ski lift would be the hypotenuse of this triangle rectangle.

Then we can use the relationship:

Sin(a) = opposite cathetus/hypoteuse.

such that:

a = 20.75°

opposite cathetus = 1200ft

then:

sin(20.75°) = 1200ft/hypotenuse

hypotenuse = 1200ft/sin(20.75°)  = 3.387.05 ft

The length of the sky lift is 3.387.05 ft

Cross multiply

Step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
