Answer:
angle 4 = 34 degrees
Step-by-step explanation:
angle 4 is equal to angle 2 because it is an alternate interior angle of 34 degrees.
Make f(x) = y
y = (15x + 50)/(x + 5)
Swap the x and y and make y the subject again
x = (15y + 50)/(y + 5)
x(y + 5) = 15y + 50
xy + 5x = 15y + 50
xy - 15y = 50 - 5x
y(x - 15) = 50 - 5x
y = (50 - 5x)/(x - 15)
So inverse function f^-1(x) = (50 - 5x)/(x - 15)
72 degrees
Since it's a regular polygon with 5 sides, you divide 360 by 5. You'd end up with 72. Hope this helps
