12^r = 13

Take the logarithm of each side of the equation:

r log(12) = log(13)

Divide each side by log(12) :

r = log(13) / log(12) = 1.03221,,, (rounded)

Can you kindly help me find the value of X? I've been getting it wrong and I need help to find out what I'm doing incorrect.

There are 360 degrees. So add the 2 angles you have: 95+45=140. Subtract that from the number of degrees: 360-140=220. X=220 :)
