Angelica says the tangent is the ratio of the length of the leg opposite Latex: ∠A
over the length of the leg adjacent to Latex:∠A . This means Latex:{BC}
must have a length of Latex: 3 units and {AC}
must have a length of Latex: 4 units. They can find the length of Latex:
AB using the Pythagorean Theorem and then use it to find the sine and cosine ratios.
