Start by identifying the hypotenuse of the right triangle. Then find the sides that are opposite and adjacent to ∠A.
4/3≈ 1.33
Practice makes perfect
For the given right triangle, we want to write the ratio for the tangent of ∠A. Let's start by identifying the hypotenuse of the triangle and the sides that are opposite and adjacent to ∠A.
We see that the length of the hypotenuse is 25. The length of the side adjacent to ∠A is 15 and the length of the side opposite to ∠A is 20. With this information, we can find the desired ratio.
