Complete the 2 column proof.
Given m<rst = 5x and m<uvw = 7x
<rstand <uvw are supplementary.
Prove x=15
m<rst=5x and m<uvw=7x <rst and <uvw are supplementary given
m<rst + <uvw = 180 definition of supplementary angles
5x+7x = 180 ?
12x=180 ?
x=15 ?
My answer:
1. Given.
2. Definition of Supplementary angles.
3. Substitution.
4. Addition of like terms.
5. Division property of equality.
