Question

B. ABCDE is a regular pentagon. Find the
following:
(1) angle 1 + angle 2 + angle 3 + angle 4 + angle 5

​

Answer 1

Pentagon is 5 sided so n= 5

interior angle= (2n-4)×90°

= (2×5 -4)×90°

=(10-4) ×90°

=6×90°

=540°

540°=a1+a2+a3+a4+a5

540/5=a (only if all angles are equal otherwise not)

:.each angle =108°
