Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved

<u><em>FALSE.</em></u><em></em>
A composite number is the opposite of a prime number. This is false because of the possibility of the following scenario:
The two numbers are 1 and a prime number.
This is because <em>one multiplied by any number is that number.</em> A prime number cannot become a composite number just because it is being multiplied by one. For example:
1 x 7 = 7 (prime)

The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
Step-by-step explanation:
When numbers are considered, their position or place value matters a lot.
When a decimal number is written, moving left from the decimal point the place value increases ten times and while moving to the right the place value decreases 10 times.
Given two numbers are:
50.8 and 18.35
In order to compare the 5 in both numbers we have to find the place value of 55 in both numbers.
So,
<u>In 50.8:</u>
The place value of 5 in 50.8 is: 50
<u>In 18.35:</u>
The place value of 5 will be: 5/100
To compare the values, we will divide the larger place value by smaller place value

Hence,
The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
