Find the value of tanθ, if cosθ = 4/5 ; 0° ≤ θ< 90°

Answer:

Step-by-step explanation:

Given

cosθ = 4/5
0° ≤ θ < 90°

In the first quadrant both sine and cosine are positive, so as tangent.

tanθ = sinθ / cosθ =
$\sqrt{1 - cos^2}$ θ / cosθ =
$\sqrt{1 - (4/5)^2}$ / 4/5 =
$\sqrt{9/25}$ / 4/5 =
3/5*5/4 =

Emma will pay $4.50 after the discount.
