Askateboarding ramp is 12 in high and rises at an angle of 17 degrees. how long is the base of the ramp?

The length of the base of the ramp is .

Given, Skateboarding ramp is 12 inch high and rises at an angle of 17 degrees.

We have to calculate the length of base of the ramp.

For this we uses trigonometric ratio,

We know that,  

Since the skateboarding ramp rises at an angle of 17 degrees. So here is 17 degree.

Now,

Hence the length of the base of the ramp is .

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

x = 12

y = 15
