Web30°+ 42° + x = 180°. x = 180°- (30° + 42°) x = 108°. And y is the exterior angle and the two opposite angles are ∠A and ∠B. So, ∠BCD = ∠A + ∠B (Exterior angle is equal to the sum of the two interior opposite angles). y = 30°+ 42°. y = 72°. We can also find it by linear pair axiom as BC is a ray on the line AD, so. WebUnit 5 2D Word Problems 2D and 3D Word Problems Compass Bearings A bearing is an angle, measured clockwise from the north direction. Example: A ship is leaving a port on a bearing of 263 degrees. After traversing 6 miles of water it changes bearing to 37 degrees. N 263⁰ θ =360⁰- 263⁰ θ = 97⁰ Port 6 miles N 37⁰ α =180⁰- 97⁰ α = 83⁰ β =83⁰- 37⁰ β = 46⁰ The …
