Question 700957
The Pythagorean Theorem states that {{{A^2 + B^2 = C^2}}}
Where A & B are the two sides of a right triangle and C is the hypotenuse.
---------------------------
For your example, let A = 5 and B = 7
{{{5^2 + 7^2 = C^2}}}
Simplify
{{{25 + 49 = C^2}}}
Combine like terms
{{{74 = C^2}}}
Take the square root of both sides
{{{sqrt(74) = C}}}
Simplify
{{{highlight(8.60 = C)}}}
