Question

Q1)
If sinƟ=
7/25,

then find cosƟ​

Answer 1

Sin theta = Side Opp. / Hypotenuse

Sin theta = 7/25 ( as given )

Side Adj. = √25^2 - 7^2

= √625 - 49

= √576

= 24

Coz theta = Side Adj. / Hypotenuse

= 24/25

Answer 2

Answer:

Given:-

Sin²theta=7/25

To find:-

cos²theta=?

STEP BY STEP EXPLANATION:-

Sin²theta+Cos²theta=1

7/25+Cos²theta=1

49/625+Cos²theta=1

Cos²theta=1-49/625

Cos²theta= 625-49/625

Cos²theta= 576/625

TAKING SQUARE ROOT,

Cos²theta=24/25
