Isandro and yvette each have a calculator. yvette starts at 100 and subtracts 7 each time. isandro on the other hand, starts at zero and adds 3 each time. if they press the keys at the same time, will their displays ever show the same number? if so, what is the number?

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
