∠A and \angle B∠B are supplementary angles. If m\angle A=(3x+16)^{\circ}∠A=(3x+16) ∘ and m\angle B=(2x+4)^{\circ}∠B=(2x+4) ∘ , then find the measure of \angle A∠A.

i think it is 18

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
