Question

if sin thetha =4/5 then find Cos thehta​

Answer 1

Answer:

cos theta = 3/5

Step-by-step explanation:

Answer 2

Answer:  3/5

Step-by-step explanation:

Given that , sinθ = 4/5

we know that, sin θ = opposite side / hypotenuse

here, hypotenuse ² = opposite side² + adjacent side²

ie, 5²= 4² + adjacent side²

by solving , we get adjacent side = √9 = 3

cosθ = adjacent side / hypotenuse

         = 3/5
