tal surveyed his classmates about the number and types of pets they owned, and the number of missing assignments in the class and their grade in the class. he created two scatterplots shown below. based on graph b, what grade would someone with 3 missing assignments have?

the answer is c)8

step-by-step explanaction:

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

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
