The measurement of angle b is 128°
The hypotenuse length is √(4*4 + 3*3) = 5 (not √7 I suppose)
The area is base*half height = 4*3/2 = 6.
In short, I don't think complex numbers really interfere here.
Answer:
- 4
Step-by-step explanation:
The conjugate of - 2 + i is - 2 - i, thus
- 2 + i + (- 2) - i
= - 2 + i - 2 - i ← collect like terms
= - 4 ← in the form a + bi with b = 0
Bryan should have split the 
into <u>four equal parts</u> (not 8). Each smaller part is 
Note how 
reduces to
Since there are 4 smaller parts or groups, this means
Refer to the diagram below.
