Example * Label each angle as either an angle of elevation or an angle of depression. [Image of a diagram with angles labeled] ∠5/∠6 ELEVATION ∠7/∠8 DEPRESSION Angles of Elevation & Depression and Alternate Interior Angles Sometimes angles of elevation or depression will be found outside of the right triangle. You can use the fact that alternate interior angles are congruent to label an angle inside of the triangle that is congruent to the angle of elevation or depression. Then you will be able to solve for the missing side length. Example * Find the value of x. Round to the nearest tenth. Tan 18° = X/2 X = 2Tan18° X = .6 km Sin27° = X/58 X = 58sin27° X = 26.3 yd
