Answer
x=-3/5 or x= -0.6
Step-by-step explanation:
Set both fraction to a common denominator
7/16 and 4/16
now add them together
7/16 + 4/16 = 11/16
now subtract that from a full cake
16/16 - 11/16 = 5/16
there are 5/16 of the cake left
Use the tangent ratio here: tan(18) = x / 4...4 tan(18) = x, and x = 1.30
