There is a formula for Sum of interior angles of a polygon:

This figure has 7 sides, n = 7

Add up all the given angles,
Subtract from 900,
This will give you value of x.
Answer:
-2/5
Step-by-step explanation:
Formula of the Slope
m = (y2 - y1)/ (x2 - x1)
(x1 , y1) = (1, 7)
(x2, y2) = (6, 5)
put values
m = (5 - 7) / (6 - 1)
m = -2 / 5
Answer:
$821
Step-by-step explanation:
A = p (1 + r/n)^nt
Where,
A = future value
P = principal = $500
r = interest rate = 10% = 0.1
n = number of periods = 12
t = time = 5 years
A = p (1 + r/n)^nt
= 500 (1 + 0.1/12)^12*5
= 500 (1 + 0.0083)^60
= 500 (1.0083)^60
= 500 (1.6420)
= 821
A = $821
