In the figure below, n || o. Find the values of z and y.
10
(sy - 9)
ܘ 2
Z
74°

z = 106, y = 23

Step-by-step explanation:

z and 74 is a supplementary angle which is equal to 180 degrees.

z + 74 = 180

z = 106

5y - 9 and z is a vertical angle, so the are equal to

each other.

5y - 9 = z

5y - 9 = 106

5y = 115

y = 23

yes

yes yes yes

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
