Step-by-step explanation:
x+45=180 [v.o.a]
x=180-45
.°.x=95
y+90=180°[v.o.a]
y=180-90
.°.y=90
Answer:
The last one.

Step-by-step explanation:
Since y is directly related to x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 81 when x = 27
k =
=
= 3
