For this case we have by definition, that the volume of a square base pyramid is given by:
Where:
L: It's the side of the base (square side)
h: It's the height of the pyramid
Substituting:
Answer:
A.) equal
B.) 10.4
C.) 6.549
D.) 30.778
Lets solve for both possibilities.
A. (2,4)
<span>-3x+5y=2x+3y
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14</span>≠16
Incorrect
B. (3,3)
<span>-3x+5y=2x+3y
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6</span>≠15
Incorrect
Neither ordered pairs work for the equation.
Answer=D
Let AB extended intersect DC extended at point E
<span>We now have right triangle BEC with E = 90 degrees </span>
<span>For triangle BEC: </span>
<span>Exterior angle at E = 90 </span>
<span>Exterior angle at C = 148 (given) </span>
<span>Exterior angle of all polygons add up to 360 degrees </span>
<span>Exterior angle at B = 360−148−90 = 122 </span>
<span>So in quadrilateral ABCD </span>
<span>B = 122 </span>
<span>D = 360−44−148−122 = 46</span>
