Which equation is graphed here? a.) 3y - x = 10 b.) x + 3y = 10 c.) 3x - y = 10 d.) 3x + y = 10 e.) -3x - y = 10

A) 3y - x = 10 is the correct answer! (I just graphed it on Desmos.com)

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
