20 points ! what is the area of the parallelogram?

ABE is a 45 45 90 right triangle

ratio of leg: hypo = a: a√2

Given hypo AB = 18√2 so leg AE = EB = 18

Area of parallelogram = bh where b = 28 and h = EB = 18

so A = 28 x 18 = 504

Answer

A = 504 square units.

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

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
