Answer:
Step-by-step explanation:
This is right triangle trig. It will help you to remember SohCoaToa:
Sinθ=opposite /hypotenuse
Cosθ=adjacent/hypotenuse
Tangentθ=opposite/adjacent
The tangent then of angle is A is the side across (opposite) angle A over the side next to (adjacent) angle A. Keep in mind that the adjacent side is NOT THE HYPOTENUSE EVER!!!!!
tangentA = 12/9
In the next one, the sin A is the side opposite A (24) over the hypotenuse (25)
In the last one, the cos A is the side adjacent to A (7) over the hypotenuse (25)
