7•?=x

x+20=p

p+x=180

80/7 or 11.429

Step-by-Step explanation:

so first we define x in terms of p (or p in terms of x)

x=180-p

replace x in the equation x+20=p with 180-p

180-p+20=p

add p to each side

200=2p

p=100

so now we can find x

180-p=x

180-100=x

x=80

say z=?

7=80/z

multiply both sides by z

7z=80

divide both sides by 7

z=80/7

?=11 3/7

4th option is correct xy=-10

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
