Answer:
\sqrt(3)[cos((4\pi )/(45))+isin((4\pi )/(45))]
Step-by-step explanation:
The first one.
Answer:
the answer is 3
Step-by-step explanation:
Given that JKV is a triangle.
We need to determine the translated image of the coordinate V using the rule 
<u>New point V:</u>
The coordinate of the point V is (4,-1)
The new point V can be determined using the rule 
Now, substituting the point (4,-1) in the rule, we get;
New point = 
Simplifying the terms, we get;
New point = 
Thus, the coordinate of the new point V is (1,5)
All I know is that your need to add 15+15 and find the radius of the circle
you all have to fine the circumeference =2 pi r, the area= pi R square
the Radius is 5ft=25ft cuz of the pi r square is 2, pi = 3.14 (value) 3.14*25ft =75 square ft shouled be your answer
