Which of the following accurately completes the missing statement and justification of the two-column proof? m∠BEC + m∠CED = m∠BED; Definition of a Linear Pair
m∠ABC + m∠BEC = m∠BED; Angle Addition Postulate
m∠ABC + m∠BEC = m∠BED; Definition of a Linear Pair
m∠BEC + m∠CED = m∠BED; Angle Addition Postulate

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

y/x of point b= y/x of point a

step-by-step explanation:

(i got the same question, this was the correct answer.)
