What are trigonometry ratios?

Trigonometric ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

various ratios are:-

  • sin=perpendicular/hypoteneuse
  • cos=base/hypotenuse
  • tan=perpendicular/base   (tan30°)=5/b
  • cot=base/perpendicular
  • sec=hypotenuse/base
  • cosec= hypotenuse/perpendicular

The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as trigonometric.

CALCULATIONS:-

The angle of elevation is 70°

using the height and distance formula

    cos∅ = base/hypotenuse

cos 70°= 0.454  

   cos∅ = base/hypotenuse

     0.454  =14/hypotenuse

hypotenuse(length of ladder)= 14/0.454

       length of ladder= 30.83 ft
