3x - X - 9 = 3(2 - x)
only solve for x :)

x=3

Step-by-step explanation:

x = 3

Step-by-step explanation:

3x - X - 9 = 3(2 - x)  (Given)

2x - 9 = 3(2 - x) (combine like terms)

2x - 9 = 6 - 3x (distributive property of equality)

5x = 15 (addition property of equality)

x = 3 (division property of equality)

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
