Answer:
1) x= -36.
2) x = 0.
Step-by-step explanation:
1) Taking the 3rd power to both sides and using the following exponent law:
we get:
So this tells us that x = -36.
2) We can distribute the power inside every term. So the left side becomes:
Now, the trick here is to remember that 
, so replacing 1 with 
, which then gives us:
, telling us that 3x = 0 and thus, x = 0.
Answer:
try using the cosine law. you have two lengths and an angle. get the value of f ( which is side length opposite to angle F)
the use sine law to get the angles. then pick the smallest angle
