Tan 42 = 12.5/x
x = 12.5 /tan 42
x =13.88
X = 4 cm
the area of trapezium is
A = (4)(6) + (1/2)(4)(9-6)
A =30 cm^2
The answer is 471 feet.
If A = man to left of balloon
<span>B = balloon </span>
<span>C = man to right of balloon </span>
<span>∠BAC = 75°20' </span>
<span>∠BCA = 49°30' </span>
<span>∠ABC = 180 - 75°20' - 49°30' = 55°10' </span>
<span>AB = 400 ft </span>
<span>Now we have to find the value of x, which is the side opposite to angle of 75°20' </span>
<span>Using Law of Sines: </span>
<span>x/sin(75°20') = 400/sin(55°10') </span>
<span>x = 400 * sin(75°20') / sin(55°10') </span>
<span>x = 471.44 </span>
<span>x = 471 ft </span>
