I don't know what the ordered pairs are here, but anyone that doesn't end with a three. Example, (1,3) is on the graph. so is (27, 3) y, will always be three:)
I believe the equation for this graph is: Y= |x- (-2)| + 3
If I'm not wrong, it should be 27cm^3. Hope this helps!!
The 3 inside angles should add up to 180. The one next to the 130 is 50 degrees.
180 = 50 + (16x + 4) + (14x + 6)
180 = 30x + 60
120 = 30x
x = 4
