Refer to the interactive gutter diagram. What area does the applet give for area when the angle is 90 Report the number, without units (Note: Since it\'s difficult to mouse to exactly 90 degrees, were looking for a rough value) e Standard page Internet Explorer O A. The area is roughly 16.0 M http//math wvu.edu/-rhansen/TrigApplets/Gutter/Gutter.html O B. The area is roughly 14.0 O C. The area is roughly 14.5 DO 4.0 O D. The area is roughly 16.5 OA 4.0 mangle BOA 85.2 O E. The area is roughly 15.5 Gutter cross sectional area 17.3

Solution

Since we have to approximate it, it looks like a rectangle

To know the area of rectangle you need it\' 2 adjacent sides.

Now, you have been given 2 adjacent sides lenghts.

So, area of the figure = DO*AO = 4*4 = 16

But, AC>OD ( note the figure)

And, CD>AO, ( again, a almost vertical AO must be smaller than a slant side which has the same vertical height as AO)

SO, the area in more than 16.

D is the correct option.
