Forgot all about trigonometry or whichever discipline it is.

Trying to get the height of a minivan (at ramp level) which have a ramp for wheelchair.

Heres the data that i have,

Ramp lenght = 52 inch, angle of ramp at floor level is 12,5 degree.
Anyone can calculate the height for me.

Thx in advance,
i am pretty confident we have people able to resolve tis pretty easily, i am too old for that [You must be logged in to view images. Log in or Register.]

look at that trigonometry calculator on the net.

Thanx got the answer i was looking for.

gotta know your cos and sin dawg

[quido]

sin(x) = opposite / hypotenuse

sin(12.5) = h / 52

h = 52 * sin(12.5)

h = 11.255

Thats what i was doing on my calculator, but kept getting -3.44, what the fuck?

[quido]

radian mode?

[Hailto]

Oh, i was in radians, not degrees. Been awhile, l0l

[Hailto]

Ya

[BigHurb]

i was going to post the calculator but i was stoned and took a movie of my cat, so yea.

[Obrae]

haha yeah first i just went to a random trigonometry page and saw all that about radians, cos and sin.

i was like yeah i remember some of that... but not enough to actually try [You must be logged in to view images. Log in or Register.]
