Hello!

When doing Sine, Cosine and Tangent the sides of the triangle tell you what to do

The hypotenuse is H
The bottom side is A
The Straight up and down side is O

For Sine you do O / H
For Cosine you do A / H
For Tangent you do O/ A

Put in the values you Sine

Sin A = 5/ 13

Put in the values for Cosine

Cos A = 12/ 13

The answer is A) Sin A = 5/ 13, cos A = 12/ 13

Hope this helps!

If sin theta = 1/2 and pi/2 < theta < pi , what are the values of cos and tan?

Answer:

cos(θ) = -(√3)/2
tan(θ) = -(√3)/3

Step-by-step explanation:

Referring to the attached short table of trig functions, we see that the reference angle with sin(θ) = 1/2 is π/6. The table also shows cosine and tangent values for that angle.

In the second quadrant, where π/2 < θ < π, the cosine and tangent are both negative. The values you seek are ...

cos(θ) = -(√3)/2

tan(θ) = -1/√3 = -(√3)/3
