(1 + i)/(1 + 2i)
To simplify this, we need to multiply both sides by the conjugate.
(1 + i)(1 - 2i)
1 - 2i - i - 3i^2
Combine like terms.
3i^2 - 3i + 1
i^2 = -1
-3i - 2 is the simplified numerator.
(1 + 2i)(1 - 2i)
1 - 2i + 2i - 4i^2
1 - 4i^2
i^2 = -2
1 + 4
5
<h3><u>The simplified expression is ((-3i)/5) + ((-2)/5)</u></h3>
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.
