Question

The Exterior angle of a pentagon are in the ratio 1:2:3:4:5. Find all the interior angles of the pentagon.​

Answer 1

Step-by-step explanation:

let the exterior angles be x+2x+3x+4x+5x

we know that

sum of all the exterior angles is always 180

therefore

15x= 180

x=12

therefore the interior angles r

180-12=168

180-2×12=156

180-3×12=144

180-4×12=132

180-5×12=120
