Answer:
The answer is 22.2
Step-by-step explanation:
the outer angles always equal 360, so all of those added together should equal 360, and when you sole the equation, you get 22.2
36/24= y/20
3/2 = y/20
(3/2) × 20 = y
3 × 10 = y
30 = y
-1
y = -1x will be the equation of this table so the slope is just -1
im guessing $300 for 20ft2
