Keith is in a hot air balloon that is 200 feet above the ground and is ascending 1.5 feet per second. Erica is in a hot air balloon that is 548 feet above the ground and is descending 1.4 feet per second. After how many seconds will the hot air balloons be the same number of feet above the ground?

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
