Issues with cos()

When trying to find the angle of A in a triangle by using:


67^2=34^2+50^2-2*34*50*cos(A°)

I get the following result:

A=4064.18

Which doesn't add up. Did I write the formular wrong or what gives?

Yes, I type it directly into CAS and press "Solve equation numerically"

I am quite new to GeoGebra, so I am not certain as to how I attach files.

Thank you very much Mr. Lambert! I will make sure to pass this on to my teacher! Have a nice day!
