Answer:
Step-by-step explanation:
<u>The interior and exterior angles are supplementary:</u>
- A + 108° = 180°
- A = 180° - 108°
- A = 72°
If you do 240/2, you will get 120.
Answer:
True
Step-by-step explanation:
Evaluating the proposed trigonometric form, we get ...
5(cos(270°) +i·sin(270°))
= 5·cos(270°) +5i·sin(270°)
= 5·0 +5i·(-2)
= 5i
The statement is true.
