Volume of the bottom cuboid = 5 x 6 x 3 = 90 ft³
Volume of the pyramid = 1/3 x 5 x 6 x 3 = 30 ft³
Total = 90 + 30 = 120 ft³
AB = X^2(3X +2)
C^2 = (x - 3)^2
AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)
= 3x^3 + x^2 + 6x - 9
The sum of the interior angles of a triangle is 180 degrees. Therefore, if we add up all of these angles, they will equal 180.
82 + 55 + x = 180
137 + x = 180
x = 43 degrees
Hope this helps!! :)
Since 1/10=10^-1, and multiplying exponents with the same base just adds the actual exponents at the top, x=2
T to the 4th power then multiply by 3.
