Use the law of sines. The sine of the given angle divided by its opposite side is equal to the sine of that unknown angle at the top left divided by the other given side (it's too small for me to read the diagram you provided). And remember, once you have two of the angles, start with 180, subtract the two angles that you do have and you will get the third angle.

Simplify 6 - (-2) - 3(-5)

seraphim [82]

So the first thing we need to do is multiply 3*-5, since order of operations dictates it (PEMDAS)

$6-(-2)-(-15)$

Now, whenever we see a minus negative number, we can think of it as adding a positive number

$6+(+2)+(+15)$

Now we just add them together

$6+2+15 = 23$

23 is the answer

Answer:

$\dfrac{-x}{3}$ should be added to the given equation.

Step-by-step explanation:

Let a is added to the given equation.

According to the given condition,

$\dfrac{5x}{6}-4+a=\dfrac{x}{2}-4\\\\a=\dfrac{x}{2}-4+4-\dfrac{5x}{6}\\\\a=\dfrac{x}{2}-\dfrac{5x}{6}\\\\a=\dfrac{3x-5x}{6}\\\\a=\dfrac{-2x}{6}\\\\a=\dfrac{-x}{3}$

So, $\dfrac{-x}{3}$ should be added to the given equation.
