Question

If sinA+cosA=7/5 ,and sinA×cosA=12/35 , then sinA=?​

Answer 1

Answer:

your question is wrong

Step-by-step explanation:

sinA+cosA=7/5.......(1)

if square on both sides of (1)..,

sin^2 A+Cos^2 A+2sinA.cosA=1+2.SinA.CosA=49/25

or, 2sinA.CosA=49/25-1=24/25

or, sinA. CosA=12/25

not ❌=12/35
