A man 2 m high observes the angles of elevation of the t ops of house and a window on its side are 45 and 60 respectively. If the top is at height of 12m above the ground , find the height.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
