If the hypotenuse right angle of a triangle is 17 inches long, one of the legs is 15 inches. find the length of the other leg

Use the Pythagorean theorem.
a^2+b^2=c^2

15^2+b^2=17^2

225+b^2=289

Subtract 225 from both sides of the equation and you get:

b^2=64

b=8

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
