Answer:

An ordinary angle is a measure of the length subtended by a one-dimensional subset of the plane. For example, an angle of 60∘ is subtended from a point by a 16 portion of a circle centered at that point. The 16 arc that subtends the angle is a one-dimensional subset of the two-dimensional plane.

Given sin x=0.5 what is cos x

irina [24]

$sinx=0,5=\frac{1}{2}$

$sin^2x+cos^2x=1$
$(\frac{1}{2})^2+cos^2x=1$
$\frac{1}{4}+cos^2x=1$
$cos^2x=\frac{3}{4}$
$cosx=\frac{\sqrt{3}}{2}$
or
$cosx=-\frac{\sqrt{3}}{2}$

To test whether an integer, $n$, is prime, it is enough to be sure that none of the primes less than or equal to the square root

IrinaK [193]

Answer:

the largest divisor is less than the square root of that number

Step-by-step explanation:

Pick any number between 900 and 950 . For example I choose 937 . Now taking the square root of 937 would give 30.61

So divide 937 with all the primes less than 30.61

937/2, 937/3, 937/5,...................937/29

29 would be the largest divisor which is less than the square root of 937 .

29< 30.61

But if you check 937 does not divide wholly with any of the primes hence it is a prime number itself.

If any number such 925 is chosen and it gets divided wholly by another prime like 5

925 /5= 185 so it is not a prime number
