Question

यदि
sin A = 2/3 तो COS A
और tanA का मान ज्ञात कीजिए​

Answer 1

Step-by-step explanation:

we know that

sin=opp/hypo

here,

sin=2/3

So,

opp=2

hypo=3

then,

adj=?

Using phythagoras theorem we can the adjacent

hypo²=opp²+adj²

let adj=x

3²=2²+x²

9=4+x²

9-4=x²

5=x²

x=√5

So, adjacent=√5

cos=adj/hypo

cos=√5/3

tan=opp/adj

tan=2/√5
