Can someone help me with this please? I need to know the measurements of the numbered angles. Please show all work on how you got your answers

def angle equals to dgf angle so it is 106 degrees. since rhombus is paralelogram then gde angle=gfe angle so since sum of inner angles is 360 in any square then GDE+GFE=360-212= 148 diagonal of rhombus is bisector of it so angle 1 and 2= 148/2= 74 and angle 4= angle 3= 148/2= 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
