Final Answer: 8
Answer:
10.9
Step-by-step explanation:
Formula = Number x 100
Percent = 6 x 100
55 = 10.91
Following shows the steps on how to derive this formula
Step 1: If 55% of a number is 6, then what is 100% of that number? Setup the equation.
6
55% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
55Y = 6 x 100
55Y = 600
Y = 600
100 = 10.91
We know that the interior angles of a trapezoid add up to 360 degrees.
Write out an equation to represent this situation;
108+108+2x+2x=360
216+4x=360
4x=360-216
4x=144
x=144/4
x=36
Therefore, the measure of x is 36 degrees.
Hope I helped :)
