An automobile company hired an advertising agency to survey its customers to find out which brand of tire they preferred for their cars. The results of the survey are displayed in the table. Which measure(s) of central tendency represents the most popular brand of tire?

A. the mean
B. the median
C. the mode
D. either the mean or the median

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
