Delta, is just a Greek letter very used in Math. It's meaning depends on the context.
But a very common meaning, specially for capital delta ( a triangle) is difference. For instance, a temperature Delta usually means the difference of the temperatures of 2 objects. In your case, it probably means the difference of the given values
Typically, delta means "change in" in math.
Graphic designers use math because they have to measure out models to a certain scale. They need to know how to calculate exact measurements.
Now a days, learning has become much easy. You can get help with concepts of math online. You can search for math help or geometry help online and get a learning from online. Try typing in "cool math 4 kids" in your search engine. That's a great website for stuff like that, but I can't think of their address right now.
The exact value of 60 degrees would be 1/2. This is a math problem.
"It is a branch of mathematics that studies the relationships involving lenghts and angles of triangles". That's what i found online.
Typically, delta means "change in" in math.
DElta means "Change" delta can be represented by a triangle
delta
Depends on the use of "delta" In math, delta is the symbol for change or difference. "change" or "difference" would be synonyms - as in "What was the delta on the forecast last month?" (ie - how much was the forecast off?). Or "the delta in revenue, month over month, was 2%"

REALLY complicated math. stuff like (Delta x Tau)={Square Root of (Delta x t squared) -- [(Delta x r squared) / (c squared)]}. (After all, Einstein was a genius.)
Uppercase and lowercase delta are used in different contexts. For example, the uppercase delta, which looks like a triangle, is often used to indicate a difference in some quantity (for example, when a quantity increases or decreases over time).

There are many meanings. The most common one is "change in". So delta x is the change in x. This form is often used in calculus where it means very small changes in x. But there is also the Dirac delta function, a fundamental mathematical underpinning for quantum physics. A delta can also be a quadrilateral which is otherwise known as an arrowhead.
