Answer the two questions in the image above for

Complementary, 65

106+x=180

Step-by-step explanation:

Complementary angles add to 90,  Supplementary angles add to 180

These are complementary angles

x+25 = 90

Subtract 25 from each side

x+25-25 =90-25

x = 65

The next questions they are supplementary angles because they add to 180

106+x=180

Subtract 106 from each side

106-106+x=180-106

x=74

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
