Measure of "an angle", d.

180-d is the supplement of the angle.

, the translation of the description into numeric symbols.

That should really seem straightforward and not be difficult to produce as written. Here is an attempt to give more help:

180-d is the supplement of measure d, because that fits the definition of "supplementary angles". The sum of angles being 180 degrees means the angles are supplementary.

Let d = the measure of the angle.
180-d = the supplement of the angle with measure d.

20 degrees more than 3 times the measure of angle d,
is symbolized as ; simple as that; no other way to explain. Remind, d is the original angle.

The description contains, "is". That is what links one number to the other number; the equality.

.
Solve for d, which is the measure of the angle; the measure which everything in the description refers.
