hypotnuse is 90

tan
Ф=15/8

= perpendicular side/base=15/8

let perpendicular side is 15x and base is 8x

then, the formula of right angle triangle is,

         (perpendicular side)^2 + (base)^2 = (hypotnuse)^2

         (15x)^2 + (8x)^2 = (90)^2

now just find the x and find the perpendicular side(15x).
