The profit (in dollars) earned by selling w apple trees is represented by w? – 4w + 14. The profit in dollars) earned by selling w pear trees is
represented by 2w + 10. Write a polynomial that represents how much
more profit is earned by selling w apple trees than w pear trees.

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
