Answer:

The missing angle is 60 degrees, the triangle is equilateral.

Step-by-step explanation:

A fact about all triangles is that their interior angles (the angles on the inside) add up to 180 degrees. Due to two other angles being already known, you can use math to find the third angle.

180 - 60 - 60 = 60

Since all of the angles are 60 degrees, they are all equal. With this, it can be found that this triangle is an equilateral triangle since all of the angles are equal, and therefore all of the side lengths are equal.

8xy= 2(2x + y) solve for y
STatiana [176]

Answer:  \displaystyle y= \frac{2\text{x}}{4\text{x} - 1}

============================================

Work Shown:

8\text{x}y= 2(2\text{x} + y)\\\\8\text{x}y= 4\text{x} + 2y\\\\8\text{x}y - 2y= 4\text{x}\\\\y(8\text{x} - 2)= 4\text{x}\\\\y= \frac{4\text{x}}{8\text{x} - 2}\\\\y= \frac{2*2\text{x}}{2(4\text{x} - 1)}\\\\y= \frac{2\text{x}}{4\text{x} - 1}\\\\

---------------

Explanation:

The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.

Then factor out y and divide both sides by (8x-2)

Afterward there's the optional steps of simplifying (as shown in the final two steps).
