Answer: 16+n

Let’s first rewrite the equation

21+(n-5)

The first thing we need to do is distribute. The + acts as a +1. Let’s multiply n • 1 and -5•1.

21+(n-5)

21+n-5

Now we need to combine like terms. Like terms are numbers that share the same variable, or lack of. In this equation, these numbers are 21 and -5.

21+n-5

16+n

This is your answer! Hope this helps comment below for more questions :)

Question 1
Scrat [10]

Answer:

17.11 meters

Step-by-step explanation:

You are using trigonometry in this problem.

The height of the flagpole represents the side <u><em>opposite</em></u> the given angle.

The base of the triangle is given as 19 meters and represents the side <u><em>adjacent</em></u> to the given angle.

Out of the main trigonomentric functions (sine, cosine, and tangent), only tangent uses both the opposite and adjacent sides.

Tan(angle) = opposite / adjacent

If we plug in what we know into that equation: <em>tan(42 degrees) = h / 19</em>

This means that <em>your answer = 19 * tan(42) = 17.11</em> meters

Alenkasestr [34]
