Answer:
Step-by-step explanation:
Slope of line passing through (2, 7) and (1, -2) = (-2-7)/(1-2) = 9
One line of symmetry an isosceles trapezoid has
4/5 = ?/45
5 times 9 = 45.
What we do to the denominator must be done to the top, as well. 4 times 9 = 36.
So, the missing number is 36.
B I assume, not 100% sure
