Final answer:
The inverse of trigonometric functions helps find angles by relating the ratios of a right triangle's sides to its angles. Hence the correct answer is option A
Step-by-step explanation:
The inverse of trigonometric functions helps find angles.
Trigonometric functions like sine, cosine, and tangent relate the angles of a right triangle to the ratios of its sides. By taking the inverse of these functions, we can determine the angle when the ratio of the sides is known.
For example, if we know that the sine of an angle is 0.5, we can use the inverse sine function (also known as arcsine) to find the angle itself.
Hence the correct answer is option A
