Complementary angles signify that the two angles will add up to 90 degrees If the sum of your complementary angles exceeds the difference by 72, the equation will look like 
, where x and y are the two different angles. You can cancel the x's out because they are on both sides, and you are left with the single variable equation, [text]y=-y+72[/tex], and when you solve for y, you find that y is 36 degrees, which means that x is 54 degrees. Since you want the smaller angle, 36 degrees would be correct.
Answer:
We know we have to pay $75 per weel plus $0.25 for each mile we traveled, from that, if we call x the miles we have travelled, the total cost would be:
As each mile we travel costs $0.25. Now that we have that expression, they ask us how many miles did we travel if we had to pay $96.25.
The only thing we have to do is replacing the C (our total cost) per $96.25 and solve the equation we get:
We hve traveled 85 miles.
