Solve x and y. Plz show work

y = 72°, x = 36°

Step-by-step explanation:

Step 1:

2x + 3x = 180°         Supplementary ∠'s

Step 2:

5x = 180°         Combine Like Terms

Step 3:

x = 180° ÷ 5         Divide

Step 4:

x = 36°      

Step 5:

3x + y = 180°        Supplementary ∠'s

Step 6:

3 ( 36 ) + y = 180°      Input x value

Step 7:

108° + y = 180°       Multiply

Step 8:

y = 180° - 108°         Subtract

y = 72°, x = 36°

Hope This Helps :)

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
