at the beginning of the academic year, a man invested 2000 dollars in a bank at 12.5% compound interest. if he withdrew 650 dollars at the end of each academic year to pay his fees, how much had he left at the beginning of the year.

you can't solve x because it is 2 linear equation and you only have one equation

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
