Answer:
117
Step-by-step explanation:
Divide by 2 to get
5^x = 7
Now take the logarithm.
x·log(5) = log(7)
x = log(7)/log(5) ≈ 1.209062
F(x) = 4 [cos (x)]^2 - 3 = 0
4[cos(x)]^2 = 3
cos(x) = √3 / 2
That happens in the first and fourth quadrants, for the angles 30 degrees and 330 degrees.
Answer: x = 30 degrees and x = 330 degrees
