Answer:
A, C
Step-by-step explanation:
Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.
Examining
A) True
Double angle 
B) False,
No further development towards a Trig Identity
C) True
Double Angle Sine Formula 
D) False No further development towards a Trig Identity

Answer:
6 pieces
Step-by-step explanation:
6x5=30
6x3=18
18-12=6
the total would be 31ft and 6 inches
Answer:
B
Step-by-step explanation:
To solve for x, we have to get x by itself. To do this, perform the opposite of what is being done to the equation.
5x+14=k
First, subtract 14 from both sides, because 14 is being added on to 5x. Subtraction is the opposite of addition.
5x+14-14=k-14
5x=k-14
Now, divide both sides by 5, because 5 and x are being multiplied. Division is the opposite of multiplication.
5x/5=k-14/5
x=k-14/5
So, the correct answer is choice B
Answer:£24
Step-by-step explanation:
Let the total money be represented by Y
Total ratio =1+2=3
Krutika's share =1/3 × Y
8= 1/3×Y
Y=8÷(1/3)
Y= 8×3
Y=£24
The total Money they won was 24
