Hope I explain myself :/
The time from 1 to 4 is 3 hours. (1-2, 2-3, 3-4).
The height you climbed is 1200 feet.
1200/3 is 400.
Your final answer should be 400ft/h
Let the angles be A and C
<span>Complimentary angles, therefor </span>
<span>A + C = 90 </span>
<span>The measurement of the complement of an angle exceeds the measure of the angle by 25% (you used a % sign so I'll use % instead of degrees) </span>
<span>C = 1.25A </span>
<span>Substitute </span>
<span>A + 1.25A = 90 </span>
<span>2.25A = 90 </span>
<span>A = 40º <----- </span>
<span>C = 50º <----- </span>
<span>------------------------------ </span>
<span>If you meant 25º </span>
<span>A + (A + 25) = 90 </span>
<span>2A + 25 = 90 </span>
<span>2A = 65 </span>
<span>A = 32.5º </span>
<span>C = 57.5º</span>
Well on this problem recall area of a rectangle is defined by:
A = lw our w = 1/6 and our l = (x +

) we have let 'x' represent our original length.


12x + 8 = 11
12x = 11 - 8
12x = 3
x =

So our original length is
