Question

2) If sin@ =7/25 ot then find cos@and ton@​

Answer 1

Step-by-step explanation:

Given that:-

Sin@=7/25

on squaring both sides

=>Sin²@=49/625

=>1-Sin²@=1-(49/625)

=>Cos²@=(625-49)/625

=>Cos²@=576/625

=>Cos@=√(576/625)

Therefore, Cos@=24/25

Now Tan@=Sin@/Cos@

=>Tan@=(7/25)/(24/25)

=>Tan@=(7×25)/(24×25)

Cancelling 25

=>Tan@=7/24

1)Cos@=24/25

2)Tan@=7/24
