We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i
Answer:
Portion of walking in degrees = 72°
Step-by-step explanation:
The question is incomplete as the diagram is not shown in the question. I have attached the full question below. Consult it to understand the solution better
First calculate the percentage of walking from a total of all activities.
Percentage of walking = 10/50 · 100%
Percentage of walking = 20%
It means the portion of the circle(pie chart) for walking should be equal to 20% of the whole circle.
We know that the whole circle is equals to 360°
Circle = 360°
We need to calculate 20% of 360°, which will represent the portion of walking in degrees.
Portion of walking in degrees = 20/100 · 360°
Portion of walking in degrees = 72°
