WebStep 1: Determine the measure of the angle adjacent to 148°. The two angles make a straight line and therefore have a sum of 180°. 180° - 148° = 32° Step 2: Add together the two known angles inside the triangle. 56° + 32° = 88° Step 3: Subtract the sum from 180°. 180° - 88° = 92° The measure of angle h is 92°. Let's Review WebThe clockwise angle on the other side is needed. Use the angle fact that angles in a full turn add to 360°. To work the bearing, subtract 130° from 360°. 360° – 130° = 230° and so, the bearing of A from B is 230°. Here is another example of bearings using interior angles. For example, find the bearing of B from A. hourly weather for lake success ny
