Solve the equation.

3(3w−4) = −20

w = ?

w= -8/9

alternative form:

w= -0.8

3(3w-4)=-20

distribute by multiplying the numbers in parenthesis by 3

9w-12=-20

add 12 to both sides

9w=-8

divide both sides by 9

w= -8/9

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
