Question

if cosa=-48/73 then what is sina=?​

Answer 1

Answer:

here is your answer

Step-by-step explanation:

Cosa = -48/73

we know,

Sin²a + Cos²a = 1

or, Sin²a + (-48/73)² = 1

or, Sin²a + 2304/5329 = 1

or, Sin²a = 1 - 2304/5329

or, Sin²a = 3025/5329

or, Sin²a = (55/73)²

or, Sina = 55/73
