The area of a rectangle is represented by the polynomial 6r^2+ 3x - 30. Which expressions
could represent the sides of the rectangle?
F 2y — 5 and 3r + 6
G 2y + 5 and 3r - 6
H 2r + 5 and 3r + 6
I 21 - 5 and 3x

2 is the right answer

I say your answer

step-by-step explanation:

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
