A) C) B D a sin a sin (y +ß) sin(y- a) a sin a sin (y +B) sin(y+a) At a point horizontal to the foot of a mountain, the angle of elevation of its summit is found to be a . After ascending 'a' meters towards the mountain up a top of inclination B, then angle of elevation is found to be y. The height of the mountainis a sin a sin (y- ß) sin(y- a) a sin a sin (y- B) sin(y+a)

At a point horizontal to the foot of a mountain, the angle of elevation of its summit is found to be a . After ascending 'a' meters towards the mountain up a top of inclination B, then angle of elevation is found to be y. The height of the mountainis answer only in terms of sine

From a point on the ground the angle of elevation of top of a tower is α. On moving 'a' meter towards the tower, the elevation changes to β. The height of the tower is:

the angle of elevation of the top of the tower standing on a Horizontal plane from a pont A is α and after walking distance d towards it the amgle of elevation is β the height of tower is

Graphs of sin x and 2 sin x are of same shape but the maximum height of thegraph of sin x is ________ the maximum height of the graph of __________

A ski resort has a lift from A to C, as shown in the figure below. Angle DAC measures 36°. Mountain officials want to build a new ski lift from B to C. The base B will be 930 feet from A, and the new lift will be 1875 feet long. What will be the measure of angle B ? Round your answer to the nearest tenth of a degree.
