Step-by-step explanation:
Area of a trapezoid is 1/2h(b1+b2)
Height is 8 in. Base 1 is 5 in and Base 2 is 10 in. Do not use the diagonal side.
For the triangle-scalene triangle area formula is bh/2 (base times height divided by 2) The base is 5 in and the height is 4 inches.
For the paralellogram multiply base by height. 6 multiplied by 5 is 30
Let the value of the vertical drop be x
cos20°=x/11
x=0.9*11
x=9.9
Thus, the length of the vertical drop is 9.9 feet
C. a-3x=0
Equations are like a balance scale. There needs to be an “=“
