Question

Pythagorean theorem: Show work please




free points!!!!

Answer 1

The therorem is:


`a^(2) + b^(2) = c^(2)`
or, solving for b:

`b = \sqrt{c^(2)-a^(2)}`


`b = \sqrt{20^(2)-15^(2)}`

`b = √(400-225)`

`b = √(175)`

`b \approx 13.23`

Answer 2

so if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7
