-- They are unequal
-- The area of the circle is (pi) (radius²) = 19.63 inches² .
-- The area of the square is (side length)² = 25 inches² .
-- The area of the square is 27.3% greater than the area of the circle.
Answer:
You add 5 each time so we just need to multiple 5 by 40 since we alredy have the first three terms.
40*5=200
21+200=221

The derivation steps and the reasons are:
-------- Addition
--------- Tangent sum identity
------- Simplify
<h3>What is the tangent sum identity?</h3>
The tangent sum identity states that:

To determine the derivation of tan(2x), we make use of the following steps.
Rewrite 2x as the addition of x and x.
So, we have:
--- step 1
Next, we apply the tangent sum identity.
Recall that:

Substitute x for a and b.
So, we have:
---- step 2
Simplify the denominator

Hence, the result of the derivation is
