Answer:
b. 44/117
Step-by-step explanation:
Calculate tan(x) and tan(y) - can use calculator, or use Pythagoras' Theorem to calculate the length of the 3rd side of the right triangle (as you already have the side opposite to the angle and the hypontenuse, since sin(x) = O/A) and then determine tan(x) using tan(x) = O/A
Then use these values in the tan sum angle trig identity formula.
see attachment for step-by-step
So you have 4 rectangles down the middle consisting of 4 (6ft x 4ft) and 2 squares on the side of 4ft x 4ft.
So you would do:
4(6 x 4) + 2(4 x 4) to get your answer. Which is 128ft.
Hope this helps! :)
