Given the expressions:
[tex]63\angle50\text{ and 21}\angle-62[/tex]Let's add the expressions.
To add the expression, let's seperate the real part and the part with the angle and add seperately.
We have:
Real part: 63 + 21 = 84
Angle: ∠50 + ∠-62 = -12
Therefore, the answer after adding both expressions is:
(84, -12)
ANSWER:
(84, -12)
