All the interior angles of a triangle always add up to 180 degrees.
3x + (2x + 20) + (4x - 20) = 180
3x + 2x + 20 + 4x - 20 = 180
3x + 2x + 4x + 20 - 20 = 180
10x = 180
x = 180/10
Therefore, x = 18

1) A mathematical ratio is known as the golden ratio. It is frequently found in nature, and when employed in a design, it encourages compositions that look organic and natural and are visually appealing.
2) The algebraic form of golden ratio is root of x2-x-1 = 0
3) The golden ratio number is approximately equal to 1.618
4) When a line is split into two equal sections, the sum of the two parts, (a) + (b), divided by (a), equals 1.618, and this is known as the Golden Ratio
5) When designing forms, logos, layouts, and other things, this formula might be useful. By dividing each number in the Fibonacci series by its direct predecessor, the golden ratio is obtained. Mathematically speaking, the quotient F(n)/F(n-1) will become closer to the limit 1.618 for rising values of n if F(n) describes the nth Fibonacci number. The golden ratio is a more popular name for this restriction.

Answer: It is not a Function
Step-by-step explanation: One input has two outputs.
Answer:
Step-by-step explanation:
Given the equation
A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so
Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.
Therefore,
