Hello folks,
I need help in clarifying simple doubt . The Tan Theta as per perpendicular 5 and base 12 comes out to be .4166. The tan inverse would be 22.61 degrees. The ncees solution gets 24.6 degree and uses the same to find friction coefficient mu .
I want to check with folks who have already given or are preparing is that a typo in ncees practice exam or not. I looked up the 2016 MDM errata and didn't found this question on that.
Any clarification would be helpful.
Thanks
