Answer and explanation:

<em>To solve this, you must find what x equals</em>

x + 2x + 7 = 3x - 7 <em>Add together any numbers that can be added on their side</em>

3x + 7 = 3x - 7  <em>Then subtract 7 from both sides to get 3x alone</em>

3x = 3x - 14 <em> Then subtract 3x from both sides to get x</em>

<h3><em>*The x's cancel each other out so you must have typed the equation wrong. Please check to see any mistakes you may have made*</em></h3>

Well first things first, you need to add like terms. So now you should have 3x+7 =3x-7. Now already looking at this, i know that there is no answer because the two 3x will cancel out, making the equation into 14=0.

Which equation can be solved to find one of the missing side lengths in the triangle?aB60512 unitsАCOS(60°) =22 믕cos(60°) = 12Su
Mekhanik [1.2K]

In a right rectangle, we have:

\sin \alpha=\frac{opposite}{hypotenuse}\cos \alpha=\frac{\text{adjacent}}{hypotenuse}

For your exercice, hypotenuse=12

The exercise also inform the angle 60°, then:

\sin \text{ 60}=\frac{\text{opposite}}{\text{hypotenuse}}=\frac{b}{12}\cos 60=\frac{adjacent}{\text{hypotenuse}}=\frac{a}{12}
