If m< 2 = 7x + 7, m< 3 = 5y, and m< 4
a. x = 140, y = 40
b. x = 40, y = 140
c. x = 19, y = 8
d. x = 8, y = 19 = 140, find the values of x and y.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
