In an equilateral triangle all the sides are equal. This means that all the angles add up to 180 degrees.
Divide 180 by 3 and you get 60.
You want an exterior angle so you cut the angle in half ( it is now 30 )
Because the base and the line are parallel (form right angle if drew line connecting them) x is equal to
90-30=60

What term can you add to 5/6x-4 to make it equivalent to 1/2x-4?

patriot [66]

$\frac{-1}{3}x$ can be added to $\frac{5}{6}x-4$ to make it equivalent to $\frac{1}{2}x-4$ .

Step-by-step explanation:

Let,

y be the term that can be added to given fraction.

Therefore;

$(\frac{5}{6}x-4)+y=\frac{1}{2}x-4$

Subtracting $\frac{5}{6}x-4$ from both sides to find y

$(\frac{5}{6}x-4)-(\frac{5}{6}x-4)+y=\frac{1}{2}x-4-(\frac{5}{6}x-4)\\\\\frac{5}{6}x-4-\frac{5}{6}x+4+y=\frac{1}{2}x+4-\frac{5}{6}x+4\\\\y=\frac{1}{2}x-\frac{5}{6}x\\\\y=\frac{3-5}{6}x\\\\y=\frac{-2}{6}x\\\\y=\frac{-1}{3}x$

$\frac{-1}{3}x$ can be added to $\frac{5}{6}x-4$ to make it equivalent to $\frac{1}{2}x-4$ .
