Question

In this question,if the sizes of the interior angles of a pentagon are2x,3x,4x,5x and 6x ,find the largest interior angles of the pentagon the answer x is 27 and then 6(27) ,how did the 6 come?

Answer 1

Step-by-step explanation:

1. 2x+3x+4x+5x+6x=180
2. 20x=180
3. x=180/20
4. x=9
5. the largest interior angle is
6. 6x= 6X9=54

Answer 2

Answer:

sunm of all angles of a pentagon =540°

2x+3x+4x+5x+6x=540°

20x=540°

X=540/20

X=27

largest interior angle =6(27)=162
