## Well Designed And Priced

I can and have done most of these formulas with a calculator over my career but I dont have to these days. I looked through a bunch of these apps and most were either poorly designed, dysfunctional in some way, or overly priced. And Im sick and tired of everything being a subscription nowadays!This app is well organized, professional in its appearance and functionality. Its also priced accordingly for something I will only use occasionally. I made a few formula calculations the old fashion way and checked them with the app. They matched as I expected and I paid fir the app…Once!!!

## Convert Ratio To Fraction

A part-to-part ratio states the proportion of the parts in relation to each other. The sum of the parts makes up the whole. The ratio 1 : 2 is read as “1 to 2.” This means of the whole of 3, there is a part worth 1 and another part worth 2.

## How To Find The Sides Of A Right Triangle

There are a few methods of obtaining right triangle side lengths. Depending on what is given, you can use different relationships or laws to find the missing side:

**Given two sides**

If you know two other sides of the right triangle, it’s the easiest option all you need to do is apply the Pythagorean theorem:

a² + b² = c²

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:

a =

if leg b is unknown, then

b =

for hypotenuse c missing, the formula is

c =

**Given angle and hypotenuse**

- sin = b / c so = arcsin
- cos = a / c so = arccos
- tan = b / a so = arctan
- cot = a / b so = arccot

## Inscribed And Circumscribed Circles

A circle can either be inscribed or circumscribed. A circle circumscribing a triangle passes through the vertices of the triangle while a circle inscribed in a triangle is tangent to the three sides of the triangle. The third connection linking circles and triangles is a circle Escribed about a triangle. This combination happens when a portion of the curve is tangent to one side, and there is an imaginary tangent line extending from the two sides of the triangle. Given A, B, and C as the sides of the triangle and A as the area, the formula for the radius of a circle circumscribing a triangle is r = ABC / 4A and for a circle inscribed in a triangle is r = A / S where S = / 2.

c. Solve for the radius of the inscribed circle.

Radius of inscribed circle = 2A / PRadius of inscribed circle = 2 / Radius of inscribed circle = 2.45 centimeters

**Final Answer:** The radius of the inscribed circle is 2.45 centimeters.

## How To Calculate The Sides Of A Triangle

If solving for a side length of a right triangle where know two side lengths, we may use the Pythagorean theorem. The Pythagorean theorem is given as:

Where *a* and *b* are the legs and *c* is the hypotenuse.

For non-right triangles, we must know three parameters of the triangle. The three known parameters may either be two side lengths and an angle or two angles and a side length.

There are several formulas we may use for solving side lengths. The most common and versatile are the *law of cosines* and the *law of sines*.

The law of cosines is split into three formulas. They are given as:**a2 = b2 + c2 2bc×cos****b2 = a2 + c2 2ac×cos****c2 = a2 + b2 2ab×cos**Where *a*, *b*, and *c* are the side lengths and *A*, *B*, and *C* are the internal angles.

The law of sines is given as:**sina = sinb = sinc**Where *a*, *b*, and *c* are the side lengths and *A*, *B*, and *C* are the internal angles.

There are other formulas available for solving triangle sides, but the law of cosines and law of sines may be leveraged in combination to solve any triangle and therefore will most commonly be used.

## How To Calculate The Angles Of A Triangle

When solving for a triangles angles, a common and versatile formula for use is called the *sum of angles*. It is given as:**A + B + C = 180**Where *A*, *B*, and *C* are the internal angles of a triangle.

If two angles are known and the third is desired, simply apply the sum of angles formula given above. If three side lengths are known, use the law of cosines. If an angle and two sides are known, use either the law of cosines or the law of sines, depending on the combination of angle and sides.

## Why Does The Cross Multiplication Calculator For Fractions Work

Cross multiplying works because you’re just multiplying both sides of the equation by 1. Since multiplying anything by 1 doesn’t change its value you’ll have an equivalent equation.

For example, look at this equation:

If you multiply both sides by 1 using the denominators from the other side of the equation you get:

Note that this doesn’t change anything, because multiplying anything by 1 doesn’t change its value. So now you have:

Since the denominators are also the same here, b × d, you can remove them and say that:

Which is the result of cross multiplying the original equation:

## How The Calculator Works

The calculator on this page is written in the programming language JavaScript which allows it to run in your devices internet browser JS engine. The JS engine running the code allows for instant answers at the click of a button.

When the calculate button is pressed, your selected solving for parameter is inputted, and the calculator determines which set of formulas will be used to solve. Then, your inputted side/angle parameters are converted to standard units and fed into the applicable formulas. This calculator is powered by the law of cosines and other basic triangle identities.

Once the desired output parameter has been calculated, the solutions units are converted if the selected unit requires so. The final answer is rounded and then printed to the applicable output area on the calculator.
