Question 728465
Given right triangle ABC, find the approximate length of side BC. BA = 2 and angle B is 90 degrees while angle C is 20 degrees. Side AC is the hypotenuse.
----
Angle C(20 degrees) is opposite side BA(2).
Draw the picture.
BC is the base and is "x"
----
tan(20) = 2/x
x = 2/tan(20) = 5.49
------------------------
Comment:
Make sure you draw a properly labeled picture when
you work these problems.
