Answer:
9
Step-by-step explanation:
Area of a triangle=(base*height)/2
1) Input the values
54=(12h)/2
2) Multiply both sides by 2
54*2=(12h/2)2
108=12h
3) Divide both sides by 12
108/12=12h/12
9=h
I hope this helps! Please comment if you have any questions.
We can re-create the quadratic equation by
(x -3) * (x -2)
x^2 -5x + 6 = 0
we know that
total of sum of arc is 360
so, sum of both arc must be 360
so, we get
now, we can solve for x
............Answer
20 high x 18 long = 360 square feet
3 windows x (4 high x 3 long) = 3 windows x 12 square feet = 36 square feet
360 - 36 (because we obviously don't paint windows) = 324
324 square feet to paint on one wall
