The formula used to solve all three is the pythagorean theorem, aka:
a^2 + b^2 = c^2
a = one of the sides, not hypotenuse
b = the other side, not hypotenuse
c = the hypotenuse (longest side)
9) We need to rearrange the equation, as x is looking for a side other than the hypotenuse. The rearranged formula would be:
a = √(c^2 - b^2)
One of the sides, b, is given as 22. The hypotenuse, c, is given as 37. Plug these numbers into the formula and solve.
a = √(37^2 - 22^2)
a = √(1368 - 484)
a = √884
a = 29.73
x = 29.73
10) Use the same rearranged formula, solving the same way
11) Use the original (not rearranged formula) and solve for the hypotenuse
