Let sin A= -3/5 with 270°&lt; A&lt; 360°. Find the following.<br> sin A/2
GREYUIT [131]

Answer:

1/sqrt10

Step-by-step explanation:

1) Find out cosA using formula (cosA)^2+(sinA)^2=1

The module of cosA= sqrt (1- (-3/5)^2)= sqrt 16/25=4/5

So cosA=-4/5 or cosA=4/5.

Due to the condition 270degrees< A<360 degrees, 0<cosA<1 that's why cosA=4/5.

2) Find sinA/2 using a formula cosA= 1-2sinA/2*sinA/2 where cosA=4/5.

(sinA/2)^2= 0.1

sinA= sqrt 0.1= 1/ sqrt10 or sinA= - sqrt 0.1= -1/sqrt10

But 270°< A< 360°, then 270/2°<A/2<360/2°

135°<A/2<180°, so sinA/2 must be positive and the only correct answer is

sin A/2= 1/sqrt10

MArishka [77]

Answer:

Option 3 is correct that is prime numbers.

Step-by-step explanation:

Even numbers are those which are divisible by 2

Prime numbers are the numbers which are divisible by 1 and the number itself

Since, we have to take only positive numbers

Carrie has taken out the set of  even number within the set of prime number

So, 2 is the only number inside this eset because 2 is even as well as prime

Hence,universal set will be prime numbers

Therefore, Option 3 is correct that is prime numbers.
