Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q =


Distance between P & R =


But in question it is given that distance between P & Q is equal to the distance between P & R. So,

Answer:
c is the correct answer
Step-by-step explanation:
Let's see what to do buddy...
_________________________________
The sum of the angles of each n-sided figure is found in the following equation :

The question's figure is 5-sindes figure
so the sum the angles equal :

So we have :


Subtract the sides of the equation minus 479


And we're done.
Thanks for watching buddy good luck.
