Answer:
It helps you see the equation in "picture" form.
Step-by-step explanation:
When you see the inequality in a graph form, most people can benefit from seeing a different version of the same problem.
To add fractions they're suppose to have the same base or denominator then u add the top
To subtract it's the same but u subtract the top
Answer:
m∠BFE = 171º
BE = 219º
Step-by-step explanation:
∠BFE is supplementary to ∠EFC
m∠BFE = 180 - 9
m∠BFE = 171º
--------------------------
The angle between two chords is equal to half the sum of the intercepted arcs:
∠BFE = (DC + BE)2
171 = (123 + BE)/2
342 = 123 + BE
219º = BE
