Answer:
-186
Step-by-step explanation:
When you add a positive number to a negative, it gets bigger (In value) . For example:
-5 + 4 = -1
-10 + 12 = 2
So for this equation, -200 + 14, all you have to do is subtract 14 from 200, which will get you 186.
Since you removed the negative, add it back to get -186

Answer:
∠DFE=119°
Step-by-step explanation:
step 1
Find the measure of angle BFD
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
so
∠BFD=(1/2)[arc BD+arc CE]
substitute the given values
∠BFD=(1/2)[38°+84°]
∠BFD=61°
step 2
Find the measure of angle DFE
we know that
∠BFD+∠DFE=180° -----> linear pair (supplementary angles)
substitute
61°+∠DFE=180°
∠DFE=180°-61°=119°
2/7x-1/7x=100
subtract the 2/7x and the 1/7x
so it would be
1/7x=100
multiply 1/7 on both sides
so
x=100 times 1/7
solve
x=100/7
x=14 2/7
