Answer:
Your answer would be the first option.
A right angle is 90 degrees
An obtuse angle is more than 90 degrees and that angle is more that 90 degrees
Every 5 minutes, you gain 4 gallons. 45/5 = 9, 9x4 equals 36, there would be 36 gallons of water in 45 minutes
10.99 +11.67+ 3.64 + 2.83 = 29.13 SO THE TAX EQUALS 87 CENTS
The pattern is n-3, so we will start from the beginning, from 1.
7, 4, 1, -2, -5, -8, -11, -14, -17, -20, -23, -26, -29, -32, -35, -38, -41, -44.
-44 is the 18th term in the sequence.
