You are an avid skateboarder and just skated down a ramp. You want to find the distance you traveled. The height of the ramp at its tallest part is 40 inches and the horizontal length is 81 inches. Calculate the distance, to the nearest whole inch, you traveled down the ramp.

c^2=a^2+b^2
c= sqrt( 40^2+81^2 )
c=90 inches

The distance would be the square-root of the sum of the squares the height of the ramp and its horizontal length. Now,40^2 +81^2=1600+6561=8161 Therefore,the distance is 8161^1/2 =90inches(aaprax)

Use the formula a^2+b^2=c^2. You want to find c^2.
(40)^2+(81)^2=8161 Take the square root to find the answer
c=90.39
You traveled 90 feet down the ramp

Hi. This is a right triangle with one side equal to 40 and one side equal to 81. Square these two numbers and add them together. This number is the hypotenuse, so find the square root of it. The number you get is the length of the hypotenuse, ALWAYS.

that ones easy ... you use the palagoreum theorum
a(squared) + b(squared) = c(squared)
so ... 40(squared) + 81 (squared) = c (squared)
1600 + 6561 = the square root of 8161
the sqare root of 8161 is 90.3
rounded to the nearest inch is 90
so you traveled 90 inches

use pythagoreans theorem
hypotenuse = square root(horiz. side squared + vertical side squared)
hypotenuse = square root(40^2 + 81 ^2)
hypotenuse = square root(1600 + 6561)
hypotenuse = square root(8161)
hypotenuse = approximately 90 inches
