You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
Fifty-three and two hundredths
*I could be wrong*
Value of x is 9 and measure of each side is 35 units.
<u>SOLUTION:
</u>
Given, Triangle QRS is an equilateral triangle.
QR is seventeen more than twice x, 
RS is 19 less than six times x, 
And QS is one less four times x, 
We have to find x and measure of each side.
Now, we know that, sides of equilateral triangle are equal,
Then 
So, value of x is 9.

Hence, value of x is 9 and measure of each side is 35.
The answer will be y=-5/2x+5
