150*1=150
150/7200=.02 km per second
First you have to solve for the other angle (3x-70) so, 3x=70 and x=70/3
now that you have the complementary angle of 70/3 degrees, subtract 180-70/3 to get 156 2/3 degrees as your final answer
12: 1.8= 20/3. => the answer is 20/3 miles
2x^2 - 8 = 0
2x^2 = 8
x^2 = 8/2 = 4
x = sqrt(4) = 2 or -2
4(2t+6)
8t+24 is the answer
