Answer:
=3x^4+3x^3−x^2−3x+15
Step-by-step explanation:
The size of the largest angle of the pentagon will be 150°.
<h3>How to illustrate the information?</h3>
A pentagon is the polygon that has five sides. It should be noted that the interior angle of a regular pentagon is 540°.
The given ratio is 2:3:4:4:5. Therefore, the size of the largest angle of the pentagon will be:
= 5/(2+3+4+4+5) × 540
= 5/18 × 540
= 150°
In this case, the size of the largest angle of the pentagon will be 150°.
