The measure of Angle E, the angle of elevation from point A to point B, is 5 ( x minus 2). The measure of Angle D, the angle of depression from point B to point A, ( x plus 14 ). Find the measure of each angle. A. measure of angle E equals 20 degrees, measure of angle D equals 20 degrees B. measure of angle E equals 6 degrees, measure of angle D equals 6 degrees C. measure of angle E equals 10 degrees, measure of angle D equals 18 degrees D. measure of angle E equals 55 degrees, measure of angle D equals 27 degrees
Question
Answer:
Angle E----------------- > is 5( x-2) angle of elevation from point A to point BAngle D----------------- > is ( x+14) angle of depression from point B to point A
D+(90°-E)=90° angles D and (90°-E) are complementary
therefore D=E
5( x-2)=x+14
5x-10=x+14
4x=24------ > x=6°
angle E=5(x-2)=5(6-2)=20°
the answer is the letter A. measure of angle E equals 20 degrees, measure of angle D equals 20 degrees
