grigory [225]
Line BCE is supplementary, which means its straight or it is 180 degrees. so you take the angle of BCF, which is 63, and subtract that from 180 to get 117, so the measure of angle FCE is 117 degrees <span />

Can you show me how to solve this problem: a. ) 16=4 to the 3rd power x -7
Ghella [55]
We assume you mean
\ \ \display{16=4^{3x-7}}
This is solved by writing 16 as a power of 4 and equating exponents.
\ 4^{2}=4^{3x-7}
  2 = 3x - 7 . . . . . equate exponents
  9 = 3x . . . . . add 7
  3 = x . . . . . divide by 3

The solution is x = 3.
