If for two regular polygons, the ratio of the number of sides is

5: 4

and dfference of the measures of internal angles in radians is

\frac{\pi}{30}

, then the number of sides of both the polygons are

\ldots . .

View answer and explanation

Correct option: A

15,12

Option B (

\sec A - \tan A

) is correct because simplifying the given expression using trigonometric identities and the given range for A leads to this result.
