How do you find the length of the leg of a triangle?

Answer 1

if you mean a right triangle then the formula is a squared + b squared = c squared. a and b are the legs and c is the hypotunese. the legs are the smallest number then the hypotenese.

An example is a=3 , b= ? and c =5

use the formula : a squared + b squared = c squared

3 squared + b squared = 5 squared

9 + b squared = 25

-9 - 9

b squared = 16

Then you have to take the squared root of 16 which is 4 and 4 is b squared.
