Answer:
<u>Trigonometric ratios</u>
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
To find sin x and cos y, we must first find the length of the <u>hypotenuse</u> (PO) of the given right triangle.
To do this, use <u>Pythagoras' Theorem:</u>
Given:
Using the found value of the hypotenuse and the trig ratios quoted above:
Therefore, 
A full circle is 360 degrees.
The circle is separated into 8 parts, so each arc is 1/8 of a circle, which equals: 360/8 = 45 degrees.
There are 2 45 degree arcs between B and C, so the arc from B to C = 45 x 2 = 90 degrees.
The answer is B.
The answer may be 7 or 12
I think that there are 4 termms if we condider onlu plus and minus as operators.
Answer:
It's B.9
Step-by-step explanation:
Because
11+9=20
20+9= 29
29+9= 38
The common difference is positive because the arithmetic sequence is increasing.
