B)24/25
C)1
D)None of these​

Answer 1

Answer:

A 7|25. is your

an

Answer 2

Answer:-

$sinA = \dfrac{7}{25}$

Explanation:-

Given:-

cosA = $\dfrac{24}{25}$

To Find:-

Value of SinA

Solution:-

$\boxed{\bold{cosA = \dfrac{Adjacent\: Side}{Hypoteneuse}}}$

From pythagoras theorem

Hypoteneuse² = Adj.side² + opp.side²

(25)² = (24)² + opp.side²

opp.side² = 25²-24²

opp.side² = 625-576

opp.side = √49

Opp.side = 7

Now,

$\boxed{\bold{sinA = \dfrac{Opposite\: Side}{Hypoteneuse}}}$

${\rightarrow}sinA = \dfrac{7}{25}$
