Question

find the number of diagonals of a regular polygon whose interior angle measures 144 degrees?

Answer 1

the answer is 35 but dunno how they get it

Answer 2

they only give the value of interior angle

Answer 3

no of sides is 360/(exterior angle) =360/(180-44) =10
hence no of diagonals is 10*(10-3) /2 = 35

Answer 4

irst find the number of sides and then for an sided poly gon
the no of diagonals = n*(n-3)/2

Answer 5

it is an n sided polygon.
180(n-2)=144n
solve for n. what is n?
