Answer:
A. 12
Step-by-step explanation:
i= use complicated conjugate to search out definite quantity of 8 + 12i
i = 12i
i= twelve × ei 90°
i = twelve × (cos 90° + i sin 90°)
r = |i| = twelve
B.40 if angles are corresponding that means they add up to be 90 degrees and 50 plus 40 equals 90
Answer:
39°
Step-by-step explanation:

and now for SUT

Answer:
17
Step-by-step explanation:
for number 10 the answer is 24 - 7 = 17
Because the answers are all in standard form, we can simply look for the intercepts of the graph.
x-int = (-6, 0)
y-int = (0, -2)
You must multiply these numbers by a coefficient to equal 12:


Solve both equations by dividing by their values:


Look for the answer with these coefficients. The answer is
-6x - 2y = 12.
