For the answer to the question above, from the equation  x^2 - 6x + 7 = 0 , b is equal to -6. The form should become y = (x-(b/2)^2) + c. (<span>b/2)^2 is equal to 9. Hence,
</span>
0 = (x - 3)^2 -9 + 7 
<span>0 = (x - 3)^2 -2
</span>2 = <span>(x - 3)^2

x should be equal to -1.5858 and -4.4142
I hope this helps</span>

Answer:

Step-by-step explanation:

3x + 7 + 9x - 43 = 180

                    12x = 216

                      x = 18

m∠4 = 3(18) + 7 = 61°

m∠5 = 9(18) − 43 = 119°
