Find the area of the following shape. you must show all work to receive credit.

shape with vertices located at negative 4 comma 0, 0 comma 4, 2 comma 2, negative 1 comma 2, and negative 1 comma 0

answer:

8

step-by-step explanation:

area abecd = δabf - trapezoid cdfe

δabf - trapezoid cdfe = (8 x 4) / 2 - ((3 + 5) x 2) / 2 = 16 - 8 = 8

answer:  

123455421

step-by-step explanation: easy

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
