Question

Find Reactions help!

Answer 1

Do you know how to draw a free-body diagram?
I'll give you a head start with the FBD.

Answer 2

From the dimensions, angle ABD is almost exactly 90 degrees, and angle ADB 30 degrees.
Isolate the members AC and BD, replace adjacent members by the corresponding reactions and draw FBD:

For member AC, take moments about A to find Fbd. Then sum Fx and Fy to find Rax and Ray.
For member BD, it is a two force member, so the force on the member is axial.
Sum Fx and Fy will reveal Rdx and Rdy.
Good luck.
By the way, the answers given (in red) are correct.
