Answer:
B. x = 2.77
Step-by-step explanation:
3^x = 21
You first look for a base for 21 that is 3 to the power of something.
21 = 3^2.77
So 3^x = 2^2.77
They have the same base so
x= 2.77
The coterminal angle to (33/10)π on the interval [0, 2π] is (13/10)π
<h3>
How to find the coterminal angle?</h3>
For any given angle A, the family of coterminal angles is defined by:
B = A + n*2π
Where n can be any integer number different than zero.
In this case, we have:
A = (33/10)π
Now we want to get a coterminal angle to A on the interval [0, 2π]. Then we need to find the value of n such that:
B = (33/10)π + n*2π
Is on the wanted interval.
If we take n = -1, then we get:
B = (33/10)π - 2π = (33/10)π - (20/10)π = (13/10)π
Which is in fact in the wanted interval.
The coterminal angle to (33/10)π on the interval [0, 2π] is (13/10)π

if i understand correctly what you mean by this question the answer could be
14/24
28/48
you can just keep multiplying the top and the bottom by the same number to get an equivalent fraction
im sorry if i understood the question wrong, i hope this helped a little bit
