Answer:
Step-by-step explanation:
We are given that:
We need to find
240 is greater than 180 and lesser than 270
OR
So, Angle lies in the 3rd quadrant and it is well known that value of sine in 3rd quadrant is negative.
Using the property :
or
Here, .
Hence, the value
The answer is letter c. x2-8x+24-[72/(x+3)]. If you do not know how to solve this using the long division method, you can always evaluate the options through the process of elimination first. Since the degree of the other factor is already 1 (x to the power of 1), you know that option d. is not the correct answer because you know that the other factor must be raised to the power of 2. That leaves us with a, b and c. Working backwards and multiplying the given factor (x+3) with the factor in b, gives us x3-5x2+72. So from there, you know that you have to eliminate 72, which can be removed when it is subtracted by itself. Letter c does just that. Try multiplying (x+3) and option c for yourself :).
Answer:
Step-by-step explanation:
Arc length of a circle is given by,
Arc length =
Here, θ = Central angle subtended by the arc
r = Radius of the circle
From the given picture,
θ = 45°
r = 1 unit
Therefore, arc length =
=
=
=
Arc length = units
= units
Angle θ has a measure =
= radians
