Question

if sinθ = 7 / 25, then find the value of cosθ and tanθ.​

Answer 1

Answer:

sol:

Step-by-step explanation:

sinθ = 7 / 25.....{ given}

(sin)^2θ + (cos)^2θ = 1.... {formula}

(7 / 25)^2 + (cos)^2θ = 1

(49 / 625) + (cos)^2θ = 1

(cos)^2θ = 1 - (49 / 625)

(cos)^2θ = (625 - 49) / 625

(cos)^2θ = 576 / 625

cosθ = root (576 / 625)

cosθ = 24 / 25

now , tanθ = (sinθ / cosθ)..(formula)

Therfore , tanθ = 7 / 25
