If tanθ = 3/4, then sinθ equals?
  1. 3/5
  2. 5/3
  3. 2/5
  4. None of these
Explanation

tanθ = opposite / adjacent = 3/4  

Make a right triangle:  

Opposite = 3, Adjacent = 4  

Find hypotenuse using Pythagoras:  

hypotenuse² = 3² + 4² = 9 + 16 = 25  

hypotenuse = 5

sinθ = opposite / hypotenuse = 3/5
