Answer:

I believe that you would shade the one in the bottom right corner, but you might want to double check

Step-by-step explanation:

you take a (x,y) coordinate from each quadrant and plug in the numbers to see if the equation is correct. If it isn't, you do not shade that quadrant.

so for example, y<1/2 x

say your coordinate is (2,1)

you plug in the numbers so that it looks like 1>1/2×2.

1/2 × 2 is 1,

so therefore this equation is incorrect because 1 is not greater than one.

See the picture attached to better understand the problem

we know that
in the right triangle ABC
sin 70°=opposite side angle 70°/hypotenuse

in this problem
opposite side angle 70°=AB
hypotenuse=AC----> 32 ft
sin 70°=AB/32------> AB=32*sin 70°-----> AB=30.07 ----> AB=30.1 ft
