Question

Solve for x using Pythagorean Theorem. SHOW YOUR WORK.
24
30

Answer 1

Ok so let’s call the 30 a and call the 24 b.

So;

a = 30
b = 24
Find x

Formula;

a square + b square = c square
The c in this case is x.

So we are gonna transpose to make x the subject.

a square + b square = c square
x square = a square - b square

Now that x is the subject we are gonna solve for x.


x square = (30 square) - (24 square)
x square = 900 - 576
x square = 324

Now we are gonna find the square root of both sides.

x square = 324
x = 18

The square root of x square is x and the square root of 324 is 18.

Therefore x = 18
