Question

if the exterior angles of a pentagon are in the ratio 1:2:3:4:5.find all the interior angles of the pentagon

Answer 1

Answer:

total interior angles : (2n-4) x90 where n=no.of sides

= (2 x 5 -4) x90 = 6 x 90=540°

ratio is 1:2:3:4:5

sum of the ratios=1+2+3+4+5 = 15

first angle = 1/15 x 540 = 36°

Second angle = 2/15 x 540=72°

third angle = 3/15 x 540 = 108°

Fourth angle = 4/15 x 540=144°

Last angle = 5/15 x 540 = 180°
