In a regular polygon, the ratio of the measure of the exterior angle to the measure of the adjacent interior angle is 2/3. how many sides does the polygon have?

2/5*180=72

360/72=5

as simple as that you just need to read on polygons

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

( give brainliest)

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
