It's A
because it can be into a decimal and then to an equation
Answer:
see explanation
Step-by-step explanation:
Using the rule of logarithms
• 
x = n ⇔ x = 
Hence
with b = 4 and n = - 2
= - 2, then
= 
← in exponential form

Answer:
a) x = 54/tan(theta)
b) theta = arctan(54/x)
Step-by-step explanation:
a) The tangent ratio is the ratio of the side opposite an acute angle in a right triangle to the adjacent side. For the angle of elevation, the adjacent side is the distance x to the flagpole. The side opposite is the 54-foot difference between the top of the man's head and the top of the flagpole. So, we have ...
tan(theta) = 54/x
Solving for x gives ...
x = 54/tan(theta)
__
b) Solving the first equation in the previous part for theta involves the inverse tangent function:
theta = arctan(54/x)
