i'm thinking that that 36 is an angle measure and not a length of a side?

you'll have to solve a system of two equations with two unknowns:
3a + b = 90
7a = b + 90
do you understand where these equations came from?

just like solving any system of linear equations, you can do elimination or substitution....
these terms ring a bell?

maybe if i write the equations this way you'll prolly be able to do elimination:
3a + b = 90
7a - b = 90
add these equations to eliminate the "b" unknown....
