WebThe 60° angle is at the top, so the "h" side is Adjacent to the angle! Step 1 The two sides we are using are A djacent (h) and H ypotenuse (1000). Step 2 SOH CAH TOA tells us to use C osine. Step 3 Put our values into the Cosine equation: cos 60° = Adjacent / Hypotenuse = h / 1000 Step 4 Solve: Start with: cos 60° = h/1000 Swap: h/1000 = cos 60° WebMay 21, 2024 · SOHCAHTOA - Finding Missing Angles Trigonometry Maths FuseSchoolIn this video we will discover how to find a missing angle in a right angle triangle, w...

WebMay 9, 2024 · In this case, if we subtract β from 180°, we find that there may be a second possible solution. Thus, β = 180° − 48.3° ≈ 131.7° . 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°.
