There are two possibilities. It could be +2.125 , and it could be -2.125 .
Answer:
The solution is:

Step-by-step explanation:
The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So



To find x, we have to apply log to both sides of the equality.
We also have that:

So






4x and 2x line along a straight line, their sum then must be 180° so
6x=180
x=30
So the angles in there are:
3(30)-5=85°
2(30)=60°
4(30)=120°
