Question

if sinA=24/25,then secA=?​

Answer 1

Answer:

sinA = 24/25

we know that

sin Ø = P/H

then by question

P=24 and H=25

By P.G.T.

H²=P²+B²

B²=25²-24²

B²= 625-576

B²=49 = 7²

B= 7

we know that

sec A = H/B

then

secA = 25/7

We can also do this by first converting sinA to cos A and then cos A to secA it will also be easy to understand and keep it remembrance.
