Which equation can be used to find B in the triangle below?

WINSTONCH [101]

9514 1404 393

Answer:

(b) tan B = 8/6

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

Then angle B is involved in tangent and cosine relationships this way:

tan B = 8/6 . . . . . . matches 2nd choice

cos B = 6/10 . . . . . matches no choices

_____

<em>Additional comment</em>

Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.

Suppose that a classmate asked you why (2x + 112 is not (4x² + 1). What is your response to this classmate?

aleksandr82 [10.1K]

The given expression is the square of a binomial, such that:

(2x + 1)^2 = 4x^2 + 4x + 1

Then the correct option is C.

<h3>Are the expressions equivalent?</h3>

We want to see if:

(2x + 1)^2

Is equivalent to (4x^2 + 1).

First, this is false, let's prove that.

We have the square of a binomial (2x + 1)^2. Remember the general formula:

(a + b)^2 = a^2 + 2ab + b^2

So if we apply this to our expression we get:

(2x + 1)^2 = (2x)^2 + 2*2x*1 + 1^2 = 4x^2 + 4x + 1

Then, the correct option is C.
