Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A pentagon has n = 5, thus
sum = 180° × 3 = 540°
Let's find x. This will allow us to find the value of the second expression.
x - 3 = 1
x = 4
Now, we can simply plug this x-value into the second expression to obtain 4^2 - 3(4) - 1 = 3.
Thus, our answer is 3.
