Yesterday, Chillville's temperature was -20°F. Brrrtown was 40°F colder than Chillville.
If Shiverland was half as cold as Brrrtown,
what was Shiverland's temperature?

what

thats not a system of equations, that is a solution

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
