Finding sides with angles

WebIn this activity, students will use sine, cosine, and tangent functions to find missing angle measures in right triangles. There is a total of 15 problems. In the first 9 problems, the students are given right triangles with two side lengths and a missing angle. There are 3 problems each requiring sine, cosine and tangent. WebWhat we know: Relative to \angle L ∠L, we know the lengths of the opposite and adjacent sides, so we can write: \tan (L) = \dfrac {\text {opposite}} {\text {adjacent}} = \dfrac {35} {65} tan(L) = adjacentopposite = 6535 But this doesn't …
