Question

Find the values of x in the following, giving brief reasons for your answers.

please help me, thank you.​

Answer 1

For the first one x= 60 degrees

Second one x= 125 degrees

Explanation:

a) To figure out this we can see that the total of angles in a 5- angled shape is 540 degrees.

So (2x X 4) + x = 540 degrees

= 9x= 540

= x = 60

b) To figure out this we can see that the total of angles in a 7- angled shape is 900 degrees.

So 60+2x+x+x+x+x+90= 900

= 150 +6x= 900

= 6x= 750

= x= 125
