Answer:

Step-by-step explanation:
Circle F and J are congruent.

Given that: m∠DFE = 80°
DFE is the central angle of the circle F.
The measure of arc GH is equal to the central angle of Circle J.
Since both circles are congruent

The measure of arc GH is 80 degrees.
Hey there!
In order to solve this, all you need to do is cancel out terms until you have n on one side of the equal sign and everything else on the other side.
14n + q = rt – 4n (add 4n to both sides to combine 4n and 14n)
18n + q = rt (subtract q from both sides)
18n = rt – q (divide both sides by 18)
n = (rt – q) ÷ 18
Hope this helped you out! :-)
