You can substitute a number in for x and compare the answer choices (not the most efficient way but it's how I would do it). Let's just say x = 5. Then the expression would equal 0.25819889. Substitute 5 in for x is the answer choices and see which one is the same.
A) simplified is 0.004 repeating
B) simplified is 0.25819889
C) simplified is 0.12
D) simplified is 1.341640786
We can see that B is the right answer
Answer:
C. 73.75.
Step-by-step explanation:
What you do is you need to move the decimal place from the .4 over to the right and also in the quotient so that you have 295/4.
You will then divide it out to get 73.75.
Answer:
0.49 radians or 28.07 degrees
Step-by-step explanation:
Please recall that the definition of the tangent of an angle is "the ratio of the length of the side opposite the angle to the length of the adjacent side, of a right triangle."
Here, opposite side length 8
tan x = ------------------------------------- = ---------
length of adjacent side 15
We use the inverse tangent function to determine the angle x from the given information:
arctan 8/15 = x
Using a calculator, we find that x = 0.49 radians.
The measure of this angle, in degrees, is found by multiplying 0.49 radians by the conversion factor
180 degrees
--------------------
pi radians
which, in this case, works out to 28.07 degrees.
