64 feet squared because 4 cubes
72 is the length d of how deep end in feet}
Every square is a rectangle<span> because it is a quadrilateral with </span>all<span> four angles right angles.</span>
Check the picture below.
bearing in mind that an angle bisector segment will cut the angle A in two equal halves, thus θ will be half of A.
2x2-3x-20=0
4-3x-20=0
2-20=-16
-3x-16=0
-3x=16
x= -5.33333
I think i did it right. i hope this helps.
