Answer: Tan (30) = b/5

Step-by-step-explanation:

To find the correct equation, we must know the formula for tan, which is tan = opp/adj

The opposite side in this case isn't the opposite of b but the opposite of the hypotenuse...

Whereas the opposite is b, but b is an unknown...

The adjacent is next to the hypotenuse...

Whereas the adjacent is 5 cm...

Now we know the values for the equations, we can now choose the correct equation:

Tan (30) = b/5

The equation that can be used to solve for b is Tan (30)= 5/b.

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 the trigonometric ratios.
