You could create the shape, then use the chamfer tool to apply the desired edges.

Something like this part attached.

First thing I notice is that your sketch is not fully constrained.

Second thing I notice is you have a bunch of repeated dimensions that are not needed. (see attached)Repeated Dimensions.png

 

 

Let's start this thing over again from scratch.

Sketch a single line horizontally from the origin over to the right and dimension it 173.015

Attach the file here.

I noticed the same thing, but didn't want to get into teaching a basic Inventor class.

First post by OP - we should get them doing the basic stuff right before they develop bad habits.

I couldn't open his part since it is done in 2013.

Wasn't aware that the sketch geometry was unconstrained.  :mansad:

 

Way to straighten him out JD!

Take a look in the browser of the part.  I added Sweep1, Sweep2 and Mirror1, before your Chamfers.  You can see where I created a sketch at the end of the straight portion and swept the triangular portion around the curve to the tip.  I did that twice and then mirrored both of those to the other side.
