Answer 1

`x=11`

Explanation:

Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)

Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)

Since the angles in a triangle add up to 180 degrees ,

`33+(180-4x)+x=180`

Remove brackets:

`33+180-4x+x=180`

Add/Subtract:

`213-3x=180`

Subtract 213 from both sides:

`213-3x-213=180-213`

`-3x=-33`

Divide both sides by -3:

`(-3x)/(-3)=(-33)/(-3)`

`x=11`
