SSC CHSL - 17th October 2020 - Shift 2 • Quantitative Aptitude • Q72

If cosec A = 25/7, then what is the value of Tan A?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e 7/24

Understanding

Tricks

Application

cosecA = 25/7 = hypotenuse/perpendicular

So

base = √(252 - 72) 

base = √(625 - 49)

base = √(576)

base = 24

Now

tanA = perpendicular/base

So

tanA = 7/24
