Answer:
a= 20 b= 160 c= 90
Step-by-step explanation:
Based on how 20 is the angle as you can see by the arrow I made the assumption that a is 20 degrees and for c my estimated guess is 90 because if you imagine how many of the 20 degree angle can fit there you get around 80-90 so I made the guess it was option C. I am sorry if this doesn't make sense I tired to understand it I hope you get the answer right. Also enjoy the rest of your day!
Step-by-step explanation:
Since <em>a</em> is the final altitude after <em>t</em> minutes, we can plug in 21,000 for <em>a</em> in the given equation.

Solve for t.
20,400 = 3400t
t = 6 minutes
