Cos B using Area and Sides A and C of Triangle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Cos B = sqrt(1-((2*Area of Triangle)/(Side A of Triangle*Side C of Triangle))^2)
cos ∠B = sqrt(1-((2*A)/(S_a*S_c))^2)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Cos B - Cos B is the value of the trigonometric cosine function of the angle B of the triangle.
Area of Triangle - (Measured in Square Meter) - The Area of Triangle is the amount of region or space occupied by the Triangle.
Side A of Triangle - (Measured in Meter) - The 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.
Side C of Triangle - (Measured in Meter) - The 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.

STEP 1: Convert Input(s) to Base Unit

Area of Triangle: 65 Square Meter --> 65 Square Meter No Conversion Required
Side A of Triangle: 10 Meter --> 10 Meter No Conversion Required
Side C of Triangle: 20 Meter --> 20 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

cos ∠B = sqrt(1-((2*A)/(S_a*S_c))^2) --> sqrt(1-((2*65)/(10*20))^2)

Evaluating ... ...

cos ∠B = 0.759934207678533

STEP 3: Convert Result to Output's Unit

0.759934207678533 --> No Conversion Required

FINAL ANSWER

0.759934207678533 ≈ 0.759934 <-- Cos B

What is a Triangle ?

A Triangle is a type of polygon, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.
