From a point 120m horizontally from the base of a building, the nagle of elevation to the top of the building is 34 degrees. Find the height of the building..
I'm having serious trouble VISUALIZING the building.
Just visualise it as a vertical line.
What it means is that from the ground, the angle between the ground and the point at the top of that line is 34 degrees.
If you draw a pic, you'll see a right angled triangle, the vertical bit is the edge of the building, the horizontal bit is the ground.
