Note that you have blue sketch geometry (actual color depends on color scheme).
Click and drag geometry.
What to you observe?
You should observe that the horizontal construction line is not constrained to Horizontal.
Add the Horizontal constraint.
Notice the change in color of the sketch geometry.
Let's add 3 more Construction lines to Sketch1.
Add two Colinear constraints between appropriate angled lines (Fusion might do this for you - if you hover over original lines you can get Fusion to add these constraints automatically - otherwise do it manually.)
Add the 16.95 dimension as shown above.
Add the line shown above. We want it vertical and if you are careful Fusion will automatically add Vertical (or Parallel to another vertical line). But it might do Perpendicular to the angled Construction line which we do not want. (Again, you can force Parallel by "scrubbing" one of the vertical lines.)
Edit: And be careful that the first point does not snap to the midpoint of the top angled construction line.
As a beginner let's just manually add the Vertical constraint and Trim the excess length.
Select the line and mash x on the keyboard to toggle to Construction.
Add the 5.635 dimension as shown above. (Click on image to enlarge.)
Now select Plane at angle and create a Workplane 90° to the 16.95 construction line.
Start a New Sketch on this new workplane and the mash p for Project and select the Construction line that we used to create the plane.
Create a Construction line from the Midpoint of and perpendicular to the Projected line.
Dimension as .6 inch.
Add 3 lines as shown below connected to the Projected line.
Add a Midpoint constraint between the bottom horizontal line in the image and the endpoint of the .6 construction line...
Change these three lines to Construction.
Now add another horizontal line being careful no to snap to the midpoints of the vertical lines.
Add a 3Point arc clicking on the endpoints first and then the end of the .6 line.
Dimension the arc as 1.05 and change the horizontal line to Construction.
(Later we might experiment with Spline rather than arc - but for now lets keep it simple.)
Having said that - I made a mistake. No problem - we will fix that now.
Click on one of the endpoints of the arc.
You will see two Coincident Constraint glyphs appear.
If you hover over one you will see the horizontal line subtly highlight.
If you hover over the other one you will see the vertical line subtly highlight - select and delete that constraint.
Repeat on the other side.
Now drag one of the endpoints...
Add a smaller 3 Point arc as shown (be careful about automatic constraints).
If not added automatically - then manually add Tangent constraints between the smaller arc and the vertical line and larger arc.
Repeat on the other side.
The sketch should once again be fully defined.
Note that with everything we have done the model is fully parametric - we can double click edit any dimension and edit (within logical reason) and the geometry automatically updates.

That is the key to parametric modeling - no assumptions!
Either the dimensions are what you want or not. If not, double click on dimension and edit to what you really really want.
Absolute precise control by designer.
Isn't absolute precise and predictable control the same technique used in Illustrator (I have never used it before)?
New problem...
You have both Construction Plane1 and Plane2 in exactly the same location.
That doesn't do us any good.
Plane2 should be here...
Oops, actually your sketch is on Plane2, so Edit the location of Plane1 instead.
Once you have edited the location of the Construction plane start a new sketch and repeat these steps
...this time with a distance of 0.675
Sketch the large arc
Dimension radius as 1.45 this time...
Add Horizontal constraint if Fusion does not add Horizontal (or Perpendicular or Parallel) for you automatically.
Now here is a pro tip...
Select Coincident constraint.
Select the vertical construction line.
Shift select the horizontal construction line at the midpoint.
This will put the midpoint of the horizontal line on the vertical line but not at the midpoint of the vertical line.
Now add the smaller tangent arcs...
Attach your progress here.

Actually - I can't see that as you did not Attach your *.f3d file here (see my example Logic Rules in Geometry.f3d file Attached below).
