A 4-sided figure has 4 corners labeled E, G, D, C starting from the top-left corner and going clockwise. A line cuts through the shape from point C to point G and contains point F. Another line cuts through the shape from E to point F. Angle C E G is a right angle.
Based on the diagram, which reason justifies this statement?

If ∠CEF is complementary to ∠DCF, then
∠DCF ≅ ∠FEG.

Complements of the same angle are congruent.
Complements of congruent angles are congruent.
Supplements of the same angle are congruent.
Supplements of congruent angles are congruent.

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
