Question

two ajacent angle add up to 150 one is five time

Answer 1

Angle 1 is 25 degree
Angle 2 is 125 degree

Answer 2

let one angle be x and the other angle be y
so x+y=150____________(eq1)

according to the question if x=5y________(eq2)

putting eq2 in eq1 we get

5y+y=150
6y=150
y=150/6
y=25

putting y's value in eq2 then we get   
x=5y   
x=5x25     
x=125
