34 +10i
Step-by-step explanation:
( 21 + 2i) + (13 + 8i) =
Add the real numbers
21+13 = 34
Add the imaginary numbers
2i+8i = 10i
The complex number is the real plus the imaginary number
34 +10i
The answer to your question is (34 + 10i)
Step-by-step explanation:
Data
(21 + 2i) + (13 + 8i) =
To solve this operation, just sum up the whole numbers and get a result then, sum up the imaginary numbers and get another result. Finally, write the result.
-Whole numbers 21 + 13 = 34
-Imaginary numbers 2i + 8i = 10i
Result (34 + 10i)
Step-by-step explanation:
1. D, because the opposite angles have to be angle to be a parallelogram
2. C, again opposite angles have to be equal. You have to plug in the different values of x and the only one that works is 21.
ex.
angle J = 3x + 20
angle J = 3(21) + 20
angle J = 83
angle L = 4x-1
angle L = 4(21)-1
angle L = 83
3. the answer is
yes: BK = DK and CK= AK
no: CK= DK and BK= AK
4. the angle would be the same since opposite so 25 degrees
5. C, because the angles are equal to 180... so draw a picture of a square right down the different angle names, they come out to equal or next to each other.
