Question

A support beam needs to be placed at a 28° angle of elevation so that the top meets a vertical beam 1.6 meters above the horizontal floor. the vertical beam meets the floor at a 90° angle. law of sines: startfraction sine (uppercase a) over a endfraction = startfraction sine (uppercase b) over b endfraction = startfraction sine (uppercase c) over c endfraction approximately how far from the vertical beam should the lower end of the support beam be placed along the horizontal floor? 3.0 meters 3.4 meters 3.9 meters 4.4 meters

Answer 1

The distance  from the vertical beam that the lower end of the support beam be placed along the horizontal floor is 3.00 m

Angle of elevation

The angle of elevation is the angle to which the eye must be raised in order to see an elevated obect at a height.

Now, we know that a right angle triangle is formed; we can obtain the distance  from the vertical beam that the lower end of the support beam be placed along the horizontal floor from;

tan 28 = 1.6/x

x = 1.6 /tan 28

x = 3.0 meters
