Calculate Side C of Triangle







Formula

The formula to calculate the Side C of Triangle (Sc) is:

\[ S_c = \sqrt{S_b^2 + S_a^2 - 2 \cdot S_a \cdot S_b \cdot \cos(\angle C)} \]

Where:

Definition

Side C of Triangle is the length of the side C of the three sides. In other words, side C of the Triangle is the side opposite to angle C.

Side B of Triangle is the length of the side B of the three sides. In other words, the side B of the Triangle is the side opposite to the angle B.

Side A of Triangle is the length of the side A, of the three sides of the triangle. In other words, the side A of the Triangle is the side opposite to the angle A.

Angle C of Triangle is the measure of the wideness of two sides that join to form the corner, opposite to side C of the Triangle.

How to calculate the Side C of Triangle

Let's assume the following values:

Using the formula:

\[ S_c = \sqrt{S_b^2 + S_a^2 - 2 \cdot S_a \cdot S_b \cdot \cos(\angle C)} \]

Evaluating:

\[ S_c = \sqrt{14^2 + 10^2 - 2 \cdot 10 \cdot 14 \cdot \cos(1.9198621771934)} \]

The Side C of Triangle is 19.7930705079099.
