The box in the vertex mean that that angle= 90 degrees
The straight line indicates that 134+a=180
a=46
b=46=90
b=44

You first need to find angle A. You can do this by noticing that it is on a straight line with the angle with a measure of 134°, which means it must be 180 - 134 because there are 180° on a straight line. 180 - 134 = 46°, which is angle A

Angle B is complementary to angle A, which means they add up to 90°. This means that you can do 90 - 46 to find angle B, which is 44°.

I hope this helps!

<h2>The answer is Option A!</h2>

$(x + 2 \sqrt{3} i)(x - 2 \sqrt{3}i )$

Let's see what complex numbers are!

$(x + 2 \sqrt{3 }i )(x - 2 \sqrt{3}i ) \\ = {x}^{2} - 2 \sqrt{3} x + 2 \sqrt{3} x - {(2 \sqrt{3} i)}^{2} \\ = {x}^{2} - {(2 \sqrt{3}i) }^{2}$

Now we know,

${i}^{2} = - 1$

So!

$= {x}^{2} - 12 \times( - 1)$

$= {x}^{2} + 12$

And thus we get the answer!

Answer:

w ≥ -22

Step-by-step explanation:

- 10 ≤ w + 12

Subtract 12 from both sides

-22 ≤ w

The inequality for w is w ≥ -22

Z=xm/y , solve for y

Hoochie [10]

y= mx/z

You isolate the variable by dividing each side by factors that don't contain the variable, which gives you the answer as "mx" as the numerator and "Z" as the denominator.
