Like, if one side of a triangle measures 5 units, how do you find the other measurements of the other two sides?

There is NO possible way to know the lengths of the other two sides. You need to know either another side length and an angle of the triangle or two angles of the triange. Then you can use trigonometry.

OK since you are only given the degrees of two side with and unknown, (X) so you can't find the lengths of any side. But the three angels of a triangle add up to 180 degrees, So let Y be the third angle x+8+x+4+y=180 2x+y+12=180 2x+y=168 x+y/2=84 y/2=84-x y=42 -x/2 so the third angle is (42-X/2) degrees Or lets see X+2+X+8+42-X/2=180 2X-X/2+52=180 2x-x/2=128 multiply each item by 2 4X-X=256 3X=256 divided by 3 x=85 1/3 that don't seen right lets see 4+85 +1/3 + 8+ 85 +1/3 -180= 2 2/3 y=42 - 85.33/2 = 2/3 Sorry somethings not right !!!!!!! but it's close must be something wrong with my math maybe you can check it and see where I went wrong

If that is the only parameter you are given, then the only triangle that you could give measurements for is an equilateral triangle, where all sides are equal.

Each side of an equilateral triangle is 5 units.

As others have mentioned, you need more information about the triangle to get the measurement of the other two sides.

You can't, without knowing the angles.

To calculate any unknown you need 3 of the 6 side/angle combinations. A triangle has 3 sides and 3 interior angles. If we know 3 of these 6 values, we can calculate the other 3.

You need a right triangle. If you have that, you can use the trig functions to solve for other sides. If not, then make a right triangle and solve for them.

With only this information, we can't find the remaining two sides.
In fact, we must also know wat kind of a triange it is and the angles of the triangle to find the other two sides.

No way.Generally you must know three elements(not all angles)
to define a triangle
