The answer is 2.5 because you need to divide it and then you get your answer
Answer:
D and A
Step-by-step explanation:
you have to work with the exponents by adding and even multiplying
Option A will be the correct answer
Answer:
-2.7
Step-by-step explanation:
to add a decimal with a negative u must sub react them and If the negative is bigger than the positive than the negative over takes the positive and the awnser is negative.
Remember: We have to work from either the LHS or the RHS.
(Left hand side or the Right hand side)
You should already know this:
1.
2.
3.
<span>So, our question is:
</span>
Plug in the first two identities I gave you.
Apply the first identity I said you needed to know on 1/(tan θ). We should get:
Multiply the first fraction by sinθ, on both the numerator and denominator.
Multiply the second fraction by cos<span>θ, on both the numerator and denominator.
</span>
Now, use the third identity I said that you needed to know to simplify the numerator.
LHS = RHS
<span>
Therefore, identity is verified.</span>
