The sum of everything is 720 degrees, because of the six sides in this figure.
We sum all angles and get 595
720 - 595 = 125
The answer is 125 degrees
In the division problem, 0.08 ÷ 2 = 0.04, the dividend is 0.08.
Remember, -(-x)=x because the negatives cancel out
so
when p=-6 and q=7
p+(-q)-3
-6+(-7)-3
-6-7-3
-13-3
-16
