Question

The angle of elevation and the angle of depression from an object on the ground to an object in the air related as:

a.greater than
b.Equal
c.Less than
d.None of these​

Answer 1

The correct option is (b). Equal

• The angle of elevation and the angle of depression from an object on the ground to an object in the air are equal as they form a pair of alternate angles.
• From figure,

               AB║CD and AC is the transversal

               $\alpha,\beta$ form pair of alternate angles

               ⇒ $\alpha=\beta$

              ⇒ angle of elevation = angle of depression

Answer 2

Answer:

EQUAL IS THE CORRECT ANSWER
