Find the value of x that makes m
n.
m
xº
2x

x = 60

Step-by-step explanation:

For the lines to be parallel, then

x and 2x are same- side interior angles and supplementary, thus

x + 2x = 180

3x = 180 ( divide both sides by 3 )

x = 60

the answer is (2x+8)²= 16

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
