To complete the square you need to halve the linear coefficient -4/2, square it, 4, and add that value, giving you:

x^2-4x+4 and that is a perfect square equal to:

(x-2)^2

kotykmax [81]

The diagram of the three angles is shown below with point U as the point where all three lines meet.

Angles property: Angles around a point add up to 360°

We set up an equation

$175+17x-3+17x+8=360$
$180+34x=360$
$34x=360-180$
$34x=180$
$x= \frac{180}{34}= \frac{90}{17}$
