determine the length of AB. AC=CD=8cm.

Question

there is a triangle ABCD. angle B is pi/6.  A to C forms a perpendicular

 

How do I get 16 as an answer?

Answer 1

We are all a little confused by the way you typed in this problem. Usually, triangles are referred to by only 3 letters which are the vertices of the triangle. The one thing that may be helpful is that pi/6 = 30 degrees, and you have a right angle somewhere in your diagram, so you may have a 30-60-90 triangle involved. If 8 represents the side opposite the 30 degree angle, them the hypotenuse is twice as much and is therefore 16.

 

Hope this may help out.
