Find the sine ratio of angle Θ. Hint: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces. (4 points) Triangle ABC is shown. AB measures 12. BC measures 13. CA measures 5. The angle formed at point C is marked theta and angle A

12/13

Step-by-step explanation:

Sine is equal to Opposite over hypotenuse. The opposite side of an angle in a triangle is the one that it does not touch. AB is the opposite side of C here.

The hypotenuse is the line that does not create the right angle. In this triangle that is BC.

We already know the measurements of these sides, so we just need to plug them in.

SinC = 12/13

step-by-step explanation:

first, eliminate the parenthesis:
