If the measure of ÐDCB = 100°, and ÐDAC = 20°, what is ÐCAB?
Arisa [49]
DCAB would be 100. I'm pretty sure DCAB would be 100 because if DDAC is 20 that means the letters D,C, and A are 5. So if D,C, and A are all equal to 5 then B is equal to 85.

Simplify the following expression:
jasenka [17]

The simplified form of this expression is <u>28 + 10i </u>

<h3>This question is an expression of imaginary numbers</h3>

Imaginary numbers are numbers that are composed of a real number and an imaginary part.

< To resolve this issue, let's remove the first parenthesis:

(3i + 4) - i + 4(6 + 2i)

3i + 4 - i + 4(6 + 2i)

< In the second parentheses, let's apply the distributive property:

3i + 4 - i + 4(6 + 2i)

3i + 4 - i + 4 . 6 + 4 . 2i

3i + 4 - i + 24 + 8i

< Finally, let's just sum the like terms, along with the real terms:

3i + 4 - i + 24 + 8i

10i + 4 + 24

10i + 28

<u>28 + 10i</u>

Therefore, the correct value will be <u>28 + 10i</u>
