Question

A support beam to be placed at a 28° angle of elevation so that the top meets a vertical beam 1.6 meters above the horizontal floor. Thanks vertical beam meets the floor at a 90° angle.
Law of sin: sin(A)/a=sin(B)/b=sin(C)/c
Approximately how far the vertical beam should the lower end of the support be placed along the horizontal floor



A)3.0 meters
B)3.4 meters
C)3.9 meters
D)4.4 meters

Answer 1

1.6/sin(28)
The answer is B
