Answer:
The first one, the third one, and the fourth one
Step-by-step explanation:
The 1st one is the Pythagorean identity. One of the most essential trig identities you have to remember.
The second one is false because A is equal to 60 and b is equal to 30 and the left side turns into 0.5 while the other side becomes -0.5.
The third one is true since it is a distinction of the identity = (OR you can simply just subtract from either side).
The fourth one is true since it's just a different version of .
2 3/4=11/4
1 3/4=7/4
11/4+7/4=18/4....18(2)/4(2)=9/2.......4 1/2
5 and 6 are true but 7 is not true. If you divide an odd number by 2 it's not going to be half of it
The prime factors of 6 are 2 and 3. So for a number to be divisible by 6, it must also be divisible by 2 and 3. Therefore, we need to check if a number is even and then check if the sum of the digits is divisible by 3. So, all of the prime factors are even, of course.
