Y varies directly with x m eans
y=kx where k is constant

y=40
x=16
find k
40=k16
divide both sides by 16
5/2=k

y=5/2x

y=-5 find x
-5=5/2x
times 2/5 both sides to cancle fraciton (5/2 times 2/5=10/10=1)
-10/5=x
-2=x

x=-2

How are the two angles below related? Drawing not to scale. Drawing is not to scale.

Phoenix [80]

we know that

Two angles are supplementary if their sum is equal to $180$ degrees

in this problem we have

$Angle\ 1=45\°$

$Angle\ 2=135\°$

$Angle\ 1+Angle\ 2=180\°$

therefore

the answer is

The two angles are supplementary
