Question

Which equation can be used to solve for b?

Tan (30)= 5/b

Tan (30)= b/5

Tan (30)=10/b

Tan (30)=b/10

Answer 1

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

Answer 2

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.
