The answer is A 5*3=15 it must be an equal proportion so 6*x =15
Answer:this is the work I’ve done so there
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:

Answer:
if thisa is a triangle then 180-30+30 = 120 degree and we say all angles on a triangle add up to 180
Then reaply the rule changing 180 to 360 on all 4 sided shapes
180(n-2) to all other shapes.
ie) pentagon 180(n-2) = 540
continue with 540-30-30 = 480 etc....
