Question 340905
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ m\angle{a}\ +\ m\angle{b}\ =\ 90^\circ]


so


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (5x\ +\ 8)\ +\ (x\ +\ 4)\ =\ 90]


Solve for *[tex \Large x], then substitute back into the expressions for *[tex \Large a] and *[tex \Large b].
