Quick question: how do I pattern this sketch to these two sides?
Create the first location by itself.
To create the second instance, select the sketch plane, press Ctrl and select the first operation's sketch.
Select Insert>Derived sketch
Locate the derived sketch at the second location.
Draw a vertical construction line on center and mirror the derived sketch to the left.
For the 2nd/3rd instance operation, select up to surface of the first instance.
Where would the axis be located at, at the intersection of those 2 construction lines or a different position? Is it important for this boss feature to be centered about this intersection maintaining a circular pitch, or is it important to break this pitch and the boss features are all the same distance from the outer wall?
How bout dis
OP wants to pattern around an irregular shape. In my view if you want to pattern around irregular shape even though feature is same, it is good to have a separate sketch for each feature.
It doesn't look to me that feature is the same. It may be created from the same sketch, but because it is an irregular pattern the geometry ends up quite different, Having a separate sketch for each feature is by definition not patterning. In this case why wouldn't the OP just create all 3 features in 1 sketch similar to what Kevin Chandler mentioned. I don't have 2019, but from what I can see your pattern is more of a regular pattern than mine. Below is an example of an irregular pattern.
Here is another option. Though I'd think this is probably further from what you actually want than the 1st one.
Sorry. This is what I meant to post.
