Answer:
The solutions are -3 and -1
Step-by-step explanation:
∵ y = -x² - 2x + 8
∵ y = 2x + 11
∴ -x² - 2x + 8 = 2x + 11
∴ -x² - 2x - 2x + 8 - 11 = 0
∴ -x² - 4x - 3 = 0 ⇒ divide both sides by -1
∴ x² + 4x + 3 = 0
∴ (x + 3)(x + 1) = 0
∴ x + 3 = 0 ⇒ x = -3
∴ x + 1 = 0 ⇒ x = -1
∴ The solutions are -3 and -1
The largest angle of the pentagon with the given ratio of angles is: 180°.
<h3>What is a Pentagon?</h3>
A pentagon is a 5-sided polygon with 5 interior angles that have a sum of 540 degrees.
If the ratio of the angles are: 1:2:2:3:4, then the largest angle would be calculated as shown below:
4/(1+2+2+3+4) × 540
4/12 × 540 = 180°
The largest angle is: 180°.
