Which multiplication equation is false? A (2a) • (21) 5 (2a) B (2a) • 0 5 0 C (2a) • 1 5 (2a) D (2a) • b 5 b • (2a)

1.0

step-by-step explanation:

i think it is 18

step-by-step explanation:

its 50 miles away from the starting point

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
