Step-by-step explanation:
x^2 + 4x + 8 = (x^2 + 4x + 4) + 4 = (x + 2)^2 + 4.
When x^2 + 4x + 8 > 5, this means (x + 2)^2 + 4 > 5.
So (x + 2)^2 > 1.
=> (x + 2) > 1 or (x + 2) < -1.
=> x > -1 or x < -3.
We first need to find the sum of the interior angles in a pentagon, which you do by doing (5 - 2) × 180, which equals 3 × 180 = 540°. Now you know that all of the angles inside the shape must add up to 540, so you can make an equation:
90 + 112 + 2x + 148 + 2x + 10 = 540
360 + 4x = 540
- 360
4x = 180
÷ 4
x = 45
I hope this helps!
