Answer:

Solution given:

$(x + \frac{b}{2a} ) {}^{2}$

Since it is a form of (a+b)²

we have

(a+b)²=a²+2ab+b²

here

a=x

b=b/2a

now

substituting value

x²+2*x*b/2a+(b/2a)²

$\bold{\green{x²+\frac{bx}{a}+\frac{b²}{4a²}}}$

In triangle NOP, Np is extended through Point P to Point Q, m < NOP =(x+17) degrees, m< PNO =(2x-4) degrees, and m< OPQ

Zigmanuir [339]

To find the measure of angle OPQ, we have two equations...
y+5x-17=180 because angles OPN and OPQ are supplementary...
AND
x+17+2x-4+y=180 because the total degrees of a triangle must add up to 180.
The equations...
5x+y=197
3x+y=167
solce the system of equations...
x=15
y=122
Since we wanted to solve for y, 122 is the answer.
The measure of angle OPQ is 122.

Sorry this took forever. The website is hard to use because I'm used to using the app:)
