63 is composite because its factors are 1,3,7,9,21, and 63 itself.
204 is my answer. Hope it helps.
<u>Answer:</u>
<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .</u>
<u>Answer:a. Since 20° is in the first quadrant, the reference angle is 20° .b. Reference Angle: the acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle being sandwiched by the terminal side and the x-axis. It must be less than 90 degree, and always positive.</u>

The rays corresponding to supplementary angles intersect the unit circles in points having the same y-coordinate, so the two angles have the same sine (and opposite cosines).</u>

Step-by-step explanation:
I got this online XD
The equation that models the amount of gas left in the car as Phan drives is and the total amount of gasoline does it take to fill her tank is 18 gallons.
Given :
- The table below shows the amount of gas left in her tank as she drives.
- Number of Hours Spent Driving (h) 3 5 7 9
- Amount of Gas Left in Tank, in gallons (g) 12 8 4 0
The following steps can be used in order to determine the equation that models the amount of gas left in the car as Phan drives and the total amount of gasoline:
Step 1 - The two-point form of the line can be used in order to determine the equation that models the amount of gas left in the car as Phan drives.
Step 2 - Now, substitute the value of and in the above expression.
Step 3 - Simplify the above equation.
Step 4 - Now, substitute the value of (h = 0) in the above equation.
Therefore, the correct option is A).
