On a map. 3 inches represents 50 miles. which proportion can be used to find the actual distance represented by 5
inches on the map?
. 3x
50 5

Step-by-step explanation:

We are told 3 inches represents 50 miles in a map:

And we need to find how many miles are represented by 5 inches. So, we can write the following relation and find the unknown value :

Finally:

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
