Answer:

Step-by-step explanation:

You can start this in may ways but let's start by isolating one of the parenthesis:

x (x² - 5) = - (x - 3)

x³ - 5x = -x + 3 (here I multiplied x for what's inside the parenthesis and the "minus" signal by the other parenthesis which was (x - 3))

x³ - 5x + x = 3

x³ -4x = 3

x³ -4x -3 = 0 (now this right here is a "depressed cubic equation" and it's one of the toughest sit of all time, so good luck with that, you might wanna take a look at this:

ytb/watch?v=rNDy2ZFvG1E

or maybe I'm doing something wrong and it's simpler than that, but whaterver...)

Find the value of x.

Hey there :)

Here we need to use Trigonometry!

The given angle is 61°
The opposite to the angle is 22
So x is the adjacent

The trigonometric ratio that uses opposite and adjacent is tan
( I have uploaded a picture to help you )

tan α = $\frac{opposite}{adjacent}$
tan 61 = $\frac{22}{adj}$
adj = $\frac{22}{tan(61)}$
adj ≈ 12.19 ≈ 12

x = 12
