Hello

elfin viper
#

Hi

#

I’m trying to know how to work it out, not really the answer

low ravine
#

That is a pentagon , the angle at centre equals to 360 degrees

#

So 360/5 = 72 degrees

elfin viper
#

Where’d you get 360 from?

#

Isn’t is 180x5?

low ravine
#

Angle at a point equals to 360

elfin viper
#

Oh

low ravine
#

So to get the angle taken by each triangle will be 360/5 since it is a pentagon( 5 sided)

elfin viper
#

Yeah I understand

low ravine
#

Once you get 72 degrees then each triangle is an isosceles tirangle ( two sides equal) - meaning base angles are equal

#

If each triangle adds up to 180 degrees and base angles are equal then ;

#

Then 180-72 = 108 degrees

#

Therefore each angle = 108 /2 = 54 degrees

elfin viper
#

So the answer would be 54?

low ravine
#

Yes 54 degrees is the correct answer

elfin viper
#

Ohh

#

I understand now

#

Thank you
