Isaac Physics

Anyone got any clue how you do this ?
https://isaacphysics.org/questions/prism_deviations_sym?board=f35c8327-ff46-456e-946d-f87f4f4ec1ad
specifically how you relate alpha to other angles

The hints 3 & 5 pretty much cover it?

Yes
One of the problems with Isaac Physics is the entry of the solution
My answer is
Deviation = A(n - 1)
I think A should be entered as ALPHA
Please someone confirm this is right
Also
Because small angle approximations are used, A must be specified in RADIANS
EXAMPLE
Vertex angle of prism is 0.1 radians whose refractive index is 1.5
Total deviation is 0.05 radians
Please confirm

See photo attached
First deviation is i-r
Second deviation i-r
Total is 2i - 2r
