Unit 2 Test Review

Solutions

1. 110\textdegree 2. 65\textdegree
3. \mathrm{m}\angle ABD=30\textdegree 4. 3x+1+4x-7=6x+35
x=41
\mathrm{m}\angle RQS=124\textdegree
5. 6x+11+3x+8=180
x=\frac{161}{9}
\mathrm{m}\angle ABD=118.\overline{3}
6. 6x+11=4x+73
x=31
7. \frac{1}{12} 8. 1
9. If two coplanar lines intersect, then they form vertical angles.
10. example: 5 11. x=4 because 4^2+4+5=25
12. \mathrm{If }\underline{x^2=4},\mathrm{ then }\underline{\underline{x=-2\mathrm{ or }x=2}}
13. If an angle does not measure between 90° and 180°, then the angle is not obtuse.
14. Y \rightarrow X \rightarrow Z \rightarrow W 15. Jason is here.
