An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) ... which is 30. As 120 ÷ 30 = 4, and 90 ÷ 30 = 3, one gets
The simplest form of set square is a triangular piece of transparent plastic ... one with 90-45-45 degree angles, the other with 30-60-90 degree angles.
The values of sine and cosine of 30 and 60 degrees are derived by analysis of the equilateral triangle. In an equilateral triangle, the 3 angles are equal and sum to 180°, therefore each corner angle is 60°. Bisecting one corner, the special right triangle with angles 30-60-90 is obtained.
The 50/30/20 budget is a simple budgeting method. You limit fixed expenses to 50% of income, save 20%, and can spend the remaining 20%. It can be hard to stick to these percentages with an average ...
For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one in which the lengths of the sides form ratios of whole numbers, such as 3 : 4 : 5, or of other special numbers such as the golden ratio.
