What is the absolute value of the complex number -4 - sqrt 2i ?

Step-by-step explanation:

Square (-4), obtaining 16.  Next, square [-sqrt(2)]i, obtaining 2.

Applying the Pythagorean Theorem, we get:

16 + 2 = 18, so that the absolute value of -4 - sqrt(2)i is sqrt 18, or 3sqrt(2).

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
