Consider the two grading schemes above, with a homework average of 81 a class participation average of 57 a test average of 93 and a final exam grade of 87. If you calculate your grade with both teachers, what would the higher of the two grades be?

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

160 cm

step-by-step explanation:

you have to add all the sides together
