Firstly, a straight line = 180 degrees.
Based on the statement above, we can create an equation of 180-95 = x
(Which is 85)
Now, we also know that all of the angles in a triangle add up to 180 degrees, so we can create this equation of 180- (85 + 50) = y
(Which is 45)
25 in exponential form: 
Factors to make 25 in exponential form: 5 * 5 = 5^2, 1 * 25 = 25^1
Division can be used. For example
50/16=3.125gallons
or you could use multiplication
50*1/16=3.125gallons
8/3 = 2 2/3 and -11/3 = -3 2/3
so the middle line is 0 and each big line is 1.
Put the first dot on 2 2/3 or right before the 3rd big line.
Put the second dot on -3 2/3 or the line right after the 4th big line going back from 0
