Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
cos(x) = 
cos(x) = 
x = 
x = 25.84
x ≈ 25.8°
12). By applying tangent rule in the given triangle,
tan(x) = 
tan(x) = 
x = 
x = 67.29°
x ≈ 67.3°
Answer:
4
Step-by-step explanation:
The period is the length of one cycle.
By cycle, I mean the smallest piece that can be traced and copied over and over to form the whole graph. If you notice the graph starts at x=0 and the curve makes a complete cycle by x=4. The cycle starts over again at x=4 and ends at x=8. I hope you are seeing the graph looks exactly the same from x=0 to x=4 as x=4 to x=8.
The length of one cycle of this graph is 4.
Please let me know if you have further questions about this question.
Thank you.
If the mean is 32 and there is 4 numbers
then the numbers add to 32x4 which is 128
128-15-21-75=17
fourth number is 17
Answer:
Square root of 37
Step-by-step explanation:
37 cannot be a root, so it will go on forever.
Answer: 5
Step-by-step explanation: Convert any mixed numbers to fractions.
Then your initial equation becomes: 1/4 x 20/1
Applying the fractions formula for multiplication,
=1/4 x 20/1 = 20/4
Simplifying 20/4, the answer is
=5
