Answer:
...
Step-by-step explanation:
1.) if supplement then its equal to 90, so subtract from 90
2.) 90-72= 18, so the asnwer is 18
39+2x+1=90
40+2x=90
2x=50
x=25
3.) x-24+29=296
x+5=296
x=291
4.)vertical angles so congruent, 107
5.) 83+4x+1=180
84+4x=180
4x=96
x=24
B*H so use the distance formula to calculate the space between each point then find the height by drawing a perpendicular line and use Pythagorean's therum.
