What is wrong with this solution?
-5m - 16 = 19
Step One:
-5m - 16 + 16 = 19 + 16
Step Two:
Solution:
m
= 7
A) -5/5 does not equal m
B) you have to divide both sides by 5 first.
C)sixteen should only be added on the left side of this equation.
D) -16 +16 does not equal 0

answer: 10 meter

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
