Answer: B. 150°
Step-by-step explanation:
The angle is obviously obtuse and is therefore greater than 90°.
This rules out A. and C.
Also, this angle is not 180° because then it would be flat.
This rules out D.
Leaving the correct answer to be B. 150°
Answer:
easy
Step-by-step explanation:
2.67 * 10^-4
2.36 * 10^11
The distance between A and B is 4/3. The formula for finding the distance is y2-y1/x2-x1.
When dividing two complex numbers on rectangular form we multiply the numerator and denominator by the complex conjugate of the denominator, because this effectively turns the denominator into a real number and the numerator becomes a multiplication of two complex numbers, which we can simplify.
