The formula to use is
n = 360/E
where
n = number of sides
E = measure of exterior angle
In our case, E = 15 so
n = 360/E
n = 360/15
n = 24
This regular polygon has 24 sides
Answer: 3.5a+5b=470 and a+b=115
Step-by-step explanation:
Answer:

Step-by-step explanation:
Here we are given two coordinates through which our lines passes through. Now we are going to use the two point form to find the equation of the line.
The two point form is given as

Here we are given two coordinates . Thus replacing them in the formula and simplifying it will give us the equation of the line.




subtracting y and adding 8 on both sides we get

Hence this is our equation of the line passing through (5,3) & (4,1)
I think the answer is this,I am not sure.....
