The length of an angle is the reaction of the opposite leg length to the hypotenuse length

C

Step-by-step explanation:

we know that

In a right triangle

The cosine of an angle x is equal to

cos (x) = / frac{adjacent / side / angle / x}{hypotenuse}

The sine of an angle x is equal to

sine (x) = / frac{opposite / side / angle / x}{hypotenuse}

The tangent of an angle x is equal to

tan (x) = / frac{opposite / side / angle / x}{adjacent / side / angle / x}

therefore

the answer is the option C
