Well if it is a supplement then that means that is has to equal 180 degrees. If one angle is two times the other and it equals to 180 you can make an equation out of this.
First you would do:
x+2x=180
Then
3x=180
Last
x=60
Therefore x will equal 60 degrees which means that angle 1 is 60 and angle 2 is 120
1980 feet because 440+220=660 and 660 times 3 is 1980

Answer:
speed of the boat = 100 mph
Step-by-step explanation:
Let x = speed of the boat
upstream speed = x - 4
downstream speed = x + 4
time = 24/(x - 4) = 26/(x + 4)
Cross multiply:
24(x + 4) = 26(x - 4)
24x + 96 = 26x - 104
104 + 96 = 26x - 24x
200 = 2x
x = 100 mph
Answer: 240 Miles
Step-by-step explanation:
My answer is correct because, if 1 cm =15 miles and the distance is 16 cm apart, then all we have to do is multiply 16 times 15 (since there are 15 miles in 1 cm and theres 16 cm.) 15 x 16=240 so the naswer is 240 Miles!
Hope This Helps!
