38. reasoning without performing the conversion, determine whether the number of
new units will be greater or less than the number of original units.
a. 3 min 20 s converted to seconds
b. 23 cm converted to inches
c. kilometers per hour converted to miles per hour

the answer will be b x² +x-1

step-by-step explanation:

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
