Because 5 is the only prime number that can be written as the sum of two other prime numbers (3 and 2).
Because sin(90°) equals 1 and cos(0°) equals 1, so 1 + 1 equals 2.
Because the sum of all angles in a triangle is always 180 degrees.
The order of operations in mathematics, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), ensures that calculations like this are performed systematically; in this case, calculations inside parentheses are done first, followed by multiplication and division from left to right.
Because multiplying 2 by 3 combines these two numbers to give a total of six.
Because a triangle with angles measuring 60°, 70°, and 50° has three different angle measurements, making it a scalene triangle.
Solving for x in this linear equation demonstrates how combining like terms and isolating the variable can quickly uncover the solution; such algebraic methods date back to ancient Babylonians around 2000 BCE, illustrating the long history of systematic problem-solving techniques.
The equation a^2 + b^2 = c^2 represents the Pythagorean theorem, which explains the relationship between the sides of a right triangle.
