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
143 is composite. To be prime it has to have only 2 divisors i.e it's self and one but since it has 4 divisors ( 143, 1, 11 and 13) it is composite.
Answer:
x=7
Step-by-step explanation:
Find slope first



m is undefined- so it is a vertical line
x=7
Answer:

Done.
Here is how you do it so they asked 120 kids and 46 of them hangs out
on Saturdays so you just do this 46/120=38%
