Question

The pentagon are in the ratio of 7:8:11:13:15, find the angles

Answer 1

Let the angles be 7x,8x,11x,13x,15x
We know that sum of all the interior angles of a polygon is 180(n-2)° where n is no. Of sides
Therefore,in pentagon sum of all the side will be 540°
Therefore,7x+8x+11x+13x+15x=540
Find the value of x and then find the angles hope it helps

Answer 2

Step-by-step explanation:

−20

4

2+7+6+x

=15

15+x=60

x=45

Now,

5

18+1+6+45+y

=10

70+y=50

y=−20
