You should draw a diagram
And it should make a triangle and solve using SOH-CAH-TOA (sin cos tan) relative to your angle of 69 degrees
Logbase11(121)=2. The base of the log to the power of y (outside number) = the number in the parenthesis (x).
You get a "sum" when you add numbers together.
First, find the lowest common denominator. That is 12. You only have to change 3/4 into 12ths.
3/4 = 9/12
11/12 – 9/12 = 2/12 = 1/6
