Answer:
7∠82°
Step-by-step explanation:
Well angle 6 and 7 are complementary angles, meaning they both add up to 180°.
So we do 180 - 98 which is 82°.
A is the correct answer because it is the only one that shows the angles that add up to 180 degrees on a line since a supplementary angle is on the line and will add up to 180. D would be correct if angles 6,4,and7 were placed together as those angles together wake a line but no, this means A is the correct answer

Answer:
1.5 hours
Step-by-step explanation:
65% ---- 1 hour
1% ---- 1/65 hours
100% ---- 1/65 ×100 = 1.5 hours (nearest half-hour)
The function f(x) shows how much Kate pays for the data service for downloading x songs in a month. So f(14) will represent the amount that Kate will have to pay for downloading 14 songs in a month.
f(x) = 2.50x + 11.50
Replacing x by 14, we get:
f(14) = 2.50(14) + 11.50 = 46.5
Thus, Kate will have to pay $ 46.5 for downloading 14 songs in a month
