Answer:
12.686cm
Step-by-step explanation:
By using pythagoras, we can find CB.
We know that 
Therefore, 
(it has to be positive since it is distance)
now we look at triangle BCD and use SOH CAH TOA.
8 because it goes from 1s 10s 100s so 8 is the answer
Answer/Step-by-step explanation:
2) There is a cluster, and as x increases, y increases.
As x increases y increases it may be confusing because it steps down and then goes back up the overall shows that the number has gone up. it is a cluster because all the numbers are in a very close group.
Y = 104°
z = 24
Angle y° and (5z - 44)° are linear pairs, meaning that the two measures together will add up to 180°.
To solve for z, know that (5z - 44)° and 76° are vertical angles, meaning that both angles are the same.
So simply set them equal to each other to find z:
5z - 44 = 76
5z = 76 + 44
5z = 120
z = 24
Now to solve for y, remember that since (5z - 44)° and 76° are vertical angles, they are the same, meaning you can denote (5z - 44)° as simply 76°. Like I said earlier, y and 76° are a linear pair so simply subtract 76 from 180 to find y:
180 - 76 = 104°
Answer:
If log x = 2
x = 100
Step-by-step explanation:
Logarithm always has a base and an index. It can be I many forms.
It can be in base 2, 3, 4, 5, and so on.
It is a property of logarithm that if
logarithm of 'a' to base 'b' equals 'x', we write:
log_b (a) = x
Then,
a = b^x.
Usually, when a logarithm is written without a base, it tells us that it is in base 10. Instead of writing a logarithm of x to base 10,we can just write 'log x', it is sufficient to say that it is in base 10.
It can also be in the form of the Napierian Logarithm, 'ln'.
'ln x' is logarithm to base 'e'.
if ln x = 5
Then
x = e^5.
So,
log x = 2
Means logarithm of 'x' to base 10 equals 2.
x = 10^2
= 100
x = 100
