Step-by-step explanation:
2-(8-5x6) = 24
Answer:
The volume of the pyramid is 
Step-by-step explanation:
we know that
The volume of the pyramid of the figure is equal to
we have
----> the height must be perpendicular to the base
substitute
The red arrows show that the lines are parallel, but using the stuff given you can make an equation.
its hard to explain without drawing but starting from the 60 if you can make a Z you will get alternate angles and that mean that the given equation MUST be equal to 60. So,
8x-4=60
8x=60+4
8x=64
x=64/8
x=8 (is your answer)
hope you understand
To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
