Answer:
I dont know the answer but I found out how you figure out if lines are supplementary
Step-by-step explanation:
1) let the measure of one of the supplementary angles be a
2) measure of the other angle is 2 times a
3) so the measure of the angle is 2a
4) if the sum of the two angles is 180 degrees then the angles are supplementary
I’m pretty sure that it is 4
12 * 5280 * 2.56 I think would give us the answer of <span>162201.6, unless I did my addition wrong</span>
Answer:
C. 9
Step-by-step explanation:
81 = 9 x 9
18 = 9 x 2
so the greatest common factor (GCF) of 81 and 18 : 9
Answer is C. 9
