Question

Can someone please help?!?!
Complete the two column proof

Given:<2=<4, m<2= 110 degrees
Prove:m∠3 = 70º

<2=<4, m<2= 110 degrees Given
m∠2 = m∠4 Definition of congruent angles
m∠4 = 110º b. ________
∠3 and ∠4 are a linear pair Definition of a linear pair (shown in diagram)
∠3 and ∠4 are supplementary Linear Pair postulate
m∠3 + m∠4 = 180º c. _______
m∠3 = 70º d. _______

Answer 1

I already figured out that c is Supplementary angles I just need help with b and d

Answer 2

you know that m<2= 110 degrees and m∠2 = m∠4

Answer 3

so why is m∠4 = 110º true?

Answer 4

refresh the page if you get weird looking symbols

Answer 5

Sorry, because it's an obtuse angle?

Answer 6

ignore the drawing

Answer 7

if m<2= 110 degrees and m∠2 = m∠4, then why is m∠4 = 110º true?

Answer 8

They are congruent?

Answer 9

what property are you using

Answer 10

The Symmetric Property

Answer 11

nope

Answer 12

Congruent Complements

Answer 13

if x = 2 and I wanted to evaluate 2x, what do I do?
