1.
the angle should add up to 360
so
360-110-90=160
that is the answer
2.
the angle has to add up to 90
so
90-57=33
The vertex would be (5,-23)
With what? there’s no problem.
M Blake will need 7 boxes. First 79 divide by 12 is 6 R6. But you can't have helf a box so you add one more box to the answer.
