Making use of the following identities
sin 2x = 2 sin x cos x
cos 2x = 2 cos^2x - 1
we can write:
Equation (1) can be factorized to give, on the right hand side:
2 cos x(sin x - cos x) + 1
Answer:
The answer is neither.
Step-by-step explanation:
The slope of AB is -5/0, and the slope of CD is 4/0.
Answer:
Two quantities can be compared by a ratio. As a fraction in the simplest form, a typical manner of expressing a ratio. If you compare the two numbers with distinct measuring units, this type of ratio is known as a rate. A rate is unit rate when it is 1. A rate is unit rate.
Step-by-step explanation:
Answer: There are five sides in a polygon.
Step-by-step explanation:
Since we have given that
Measure of exterior angles = 72°
We need to find the number of sides of polygon.
As we know the formula for "Number of sides of polygon".
Number of sides is given by
Hence, there are five sides in a polygon.
