WebMar 26, 2016 · Select names for the acute angles in order to determine the opposite and adjacent designations. The easiest way to do this is to draw a picture and label it. The two acute angles are named with the Greek letters theta and lambda. The side opposite theta measures 7 inches, and the side adjacent to it measures 24 inches. WebSep 1, 2024 · To check the solution, subtract both angles, 131.7° and 85°, from 180°. This gives α = 180 ∘ − 85 ∘ − 131.7 ∘ ≈ − 36.7 ∘ which is impossible, and so β ≈ 48.3°. To find the remaining missing values, we calculate α = 180° − 85° − 48.3° ≈ 46.7° . Now, only side a is needed. Use the Law of Sines to solve for a by one of the proportions.
