Question

How do you solve for a leg of a right triangle using pythagorean theorem?

Answer 1

Do you know the other two sides of the triangle?
Or, the triangle a 30-60-90 triangle?

The answer depends upon knowing more about the triangle.

Answer 2

18, 15, and x. 18 being the hypotenuse.

Answer 3

pythag: \[(L_1)^2+(L_2)^2=(Hypot)^2\]

rearrange for a leg
\[(L_2)^2=(Hypot)^2-(L_1)^2\]

Answer 4

so i would do \[x^2 = 18^2-15^2\] ?

Answer 5

correct, then of course take the sqrt of each side

Answer 6

okay thank you!

Answer 7

;) youre welcome

Answer 8

i got 99, so what would i do for the square root?
