What trig ratio should be used to calculate either side a or o?
-
Sin Ï´
-
Cos Ï´
-
Tan Ï´
Correct Answer
A. Tan Ï´Explanation
The tangent ratio should be used to calculate either side a or o. The tangent of an angle is defined as the ratio of the length of the side opposite the angle (o) to the length of the side adjacent to the angle (a). Therefore, by using the tangent ratio, we can calculate either side a or o depending on the information given in the problem.Rate this question:

What trig ratio should be used to calculate either side h or o?
-
Sin Ï´
-
Cos Ï´
-
Tan Ï´
Correct Answer
A. Sin Ï´Explanation
To calculate either side h or o, the trig ratio that should be used is Sin Ï´. The sine function relates the ratio of the length of the side opposite the angle Ï´ to the length of the hypotenuse. In a right triangle, the side opposite Ï´ is represented by h, and the hypotenuse is represented by o. Therefore, using the sine function (Sin Ï´) will allow us to calculate either side h or o.Rate this question:
