Aroller coaster carries riders up a ramp that is 39 meters long. this ramp
forms a right triangle with the ground and a vertical support beam. what is
the height of the support beam?
support
roller coaster 9
ground
15 m

a. 36 m
24 m
c. 42 m
d. 54 m

A. 36

Step-by-step explanation:

By using hypotenuse theorem we can find the height of the support.

In hypotenuse we square both the given measures, then subtract them. if slant measure is given we subtract the square of the other side from the square of the slant and find the square root of the result. if we have to find the slope, then we add the squares of the 2 given sides and find the square root of the result.

so, in this case:

(39×39) - (15×15)

=1521 - 225

=1296

= square root of 1296

= 36

Hope it helps u

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
