Answer 1

a^2+b^2=c^2(the longest side of right triangle ) use the equation to find r plugin a b ,c values

Answer 2

I need to find a tho

Answer 3

adjacent side is `r`
base is `r`
hypotenuse is `15 ` in

therefore,
\[\large\rm \color{Red}{a=r}~ ,~\color{blue}{ b=r },~ \color{green}{ c=15} \]
\[\large\rm \color{Red}{a}^2~ +~\color{blue}{ b }^2=~ \color{green}{ c}^2 \]
