I need the force in memebers DE$,$DC$,$EA$,$EC$,$CF$,$CB$,$BA$,$FA$,$BF and need to know whether in tension or compression

Consider the truss shown in $($Figure $1).$

Part A

Determine the force in member $DE$ of the truss and state if the member is in tension or compression.

Part B

Determine the force in member $DC$ of the truss and state if the member is in tension or compression.

Part C

Determine the force in member $EA$ of the truss and state if the member is in tension or compression
