The area of Marcia's trapezoid felt is 76.5 sqaured centimeters
Solve like an equation,
You need x by itself.
Since x is on the denominator, multiply both sides by x to clear the fraction.
Tan 12 = 10/x
x Tan12 = 10
Divide both sides by Tan12
x = 10/(Tan12)
x = 47

Step-by-step explanation:
9/x=x-4
x² -4x - 9=0

(x -2)²=13
x-2= ±√13
x= 2±√13
