Smaller Angle of Scalene Triangle Solution

STEP 0: Pre-Calculation Summary
Formula Used
Smaller Angle of Scalene Triangle = acos((Longer Side of Scalene Triangle^2+Medium Side of Scalene Triangle^2-Shorter Side of Scalene Triangle^2)/(2*Longer Side of Scalene Triangle*Medium Side of Scalene Triangle))
Smaller = acos((SLonger^2+SMedium^2-SShorter^2)/(2*SLonger*SMedium))
This formula uses 2 Functions, 4 Variables
Functions Used
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
acos - The inverse cosine function, is the inverse function of the cosine function. It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., acos(Number)
Variables Used
Smaller Angle of Scalene Triangle - (Measured in Radian) - The Smaller Angle of Scalene Triangle is the measure of the wideness of sides that join to form the corner opposite the shorter side of the Scalene Triangle.
Longer Side of Scalene Triangle - (Measured in Meter) - The Longer Side of Scalene Triangle is the length of the longer side out of the three sides. In other words, the longer side of the Scalene Triangle is the side opposite to the larger angle.
Medium Side of Scalene Triangle - (Measured in Meter) - The Medium Side of Scalene Triangle is the length of the second longer side out of the three sides.
Shorter Side of Scalene Triangle - (Measured in Meter) - Shorter Side of Scalene Triangle is the length of the shorter side out of the three sides. In other words, shorter side of the Scalene Triangle is the side opposite to the smaller angle.
STEP 1: Convert Input(s) to Base Unit
Longer Side of Scalene Triangle: 20 Meter --> 20 Meter No Conversion Required
Medium Side of Scalene Triangle: 14 Meter --> 14 Meter No Conversion Required
Shorter Side of Scalene Triangle: 10 Meter --> 10 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Smaller = acos((SLonger^2+SMedium^2-SShorter^2)/(2*SLonger*SMedium)) --> acos((20^2+14^2-10^2)/(2*20*14))
Evaluating ... ...
Smaller = 0.482765923325734
STEP 3: Convert Result to Output's Unit
0.482765923325734 Radian -->27.6604498993061 Degree (Check conversion here)
FINAL ANSWER
27.6604498993061 27.66045 Degree <-- Smaller Angle of Scalene Triangle

What is a Scalene Triangle ?

A triangle with all sides are distinct in length is called a Scalene Triangle. Mainly triangles are classified into three on the basis of side lengths. If all sides are equal in length then it is called Equilateral Triangle. If only two sides are equal in length then it is called Isosceles Triangle. If no sides are equal, or all sides are distinct in length then it is called Scalene Triangle. Cases are similar in terms of angles also. That is, Equilateral Triangles have all three angles equal. Isosceles Triangles have atleast two angles are equal. And then, Scalene Triangles have all three angles are distinct.

Standard notations

Let a triangle is named as ABC. Then A, B and C represent respective angles of the triangle. They are usually called angle A, angle B and angle C respectively. The sides opposite to angles A, B and C are respectively called side a, side b and side c.
