Question

In right triangle QRS,the measure of an angle R is 90. Which ratio represents tan Q

Answer 1

tan(Q) = RS/RQ

Explanation:

The mnemonic SOH CAH TOA reminds you that ...

... Tan = Opposite/Adjacent

The side opposite angle Q is RS. The side adjacent is RQ. (QS is the hypotenuse, which does not come into play in the tangent function.)

Then ...

... tan(Q) = Opposite/Adjacent = RS/RQ
