How to calculate Crown Angle and Pavilion Angle from IGI Report?

I'm looking at this Oval Brilliant and with the IGI, how can I find the Crown Angle and Pavilion Angle?

Is this a good lab grown diamond? I saw it in person and it honestly looked the same compared to the other 3 diamond I saw. I think this lab grown diamond was quoted ~$1,500-$1700.
