This happens whenever the terminal point of

lies in either the first or second quadrants.
Meanwhile,

since you already know sine is positive. Cosine is positive when the angle lies in the first or fourth quadrant.
Sine and cosine are both positive only when

is the first quadrant, which means this angle's terminal point lies in the first quadrant (A).
First, find the nth term
To do this, find the term to term difference...
A
-7 and 3 = 10
3 and 13 = 10
13 and 23 = 10
As the difference is 10, we now write out the 10 times table
10, 20, 30, 40
The next step is to work out how to get from the sequence to the 10x table
B
-7 - 10 = -17
3 - 20 = -17
13 - 30 = -17
23 - 40 = -17
Now use the answer from each section in the general formula
x = An + B
This could also be written as ?n + ?
Using our numbers, this becomes 10n - 17
Now use the formula to work out the 110th term
(10 x 110) - 17
1100 - 17 = 1083
Answer:
x = 
Step-by-step explanation:
In order to find the hypothenuse, you need to do
. Which equals 164. Therefore, since
, a=8, b=10, and c=
.
1+1 = 2 that is the answer
