Answer 1

you like these i see. pythagoras gives you the missing side of the little triangle. it is a 3,4,5 right triangle, yes?

Answer 2

entire triangle is congruent to little 3, 4, 5 triangle, so compare any ratios. for example
\[\frac{x+3}{5}=\frac{5}{3}\]

\[3(x+3)=5\times 5\]
\[3x+9=25\]
\[3x=16\]
\[x=\frac{16}{3}\]
