Answer 1

heya mate !!

here is your answer :--
________________________

A vertical flag staff stand on a horizontal plane from a point = 100 m

The angel of elevation of it's top is found to be 45°

Height of the flag staff = ?

________________________

On putting these values ::--

===> tan 45°

===> tan 45° = 1/1

===> perpendicular / base = 1/1

===> perpendicular/ 100 = 1/1

===> perpendicular = 100

===> perpendicular = height = 100

===> height = 100
