I'M IN NEED OF HELP. Find the measure of each numbered angle.

3x = 77.75 9x = 233.25

Step-by-step explanation:

all of the angled inside the quadrilaterals need to add up to 360º

I am assuming the 1 on the top is an angle... it is missing a degrees sign

1 + 3x + 9x + 48 = 360

1 + 12x = 312

12x = 311

x = 25.916

plug x into the angles to find them...

You can double check if this is correct by adding them all together at the end and see if it equals 360

Hope this helps!!

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
