Answer:
below
Step-by-step explanation:
If line C is parallel to another line, they will have the same slope. so calculate the slope first:
8-2/8-0=3/4(simplified)
and thats it
sum=(n-2)*180
sum=(4-2)*180
sum=2*180
sum=360º
if T=K, T=100º
360-(100+100+20)=E
E=360-220
E=140º
37) -1/3
38) 8/5
39) 0
40) -2/3
