Side A of Triangle given Two Sides and Two Angles A and B Solution

STEP 0: Pre-Calculation Summary

Formula Used

Side A of Triangle = (Side C of Triangle-Side B of Triangle*cos(Angle A of Triangle))/cos(Angle B of Triangle)
S_a = (S_c-S_b*cos(∠A))/cos(∠B)
This formula uses 1 Functions, 5 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)

Variables Used

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.
Side B of Triangle - (Measured in Meter) - The Side B of Triangle is the length of the side B of the three sides. In other words, the side Bof the Triangle is the side opposite to the angle B.
Angle A of Triangle - (Measured in Radian) - Angle A of Triangle is the measure of the wideness of two sides that join to form the corner, opposite to the side A of the Triangle.
Angle B of Triangle - (Measured in Radian) - Angle B of Triangle is the measure of the wideness of two sides that join to form the corner, opposite to side B of the Triangle.

STEP 1: Convert Input(s) to Base Unit

Side C of Triangle: 20 Meter --> 20 Meter No Conversion Required
Side B of Triangle: 14 Meter --> 14 Meter No Conversion Required
Angle A of Triangle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Angle B of Triangle: 40 Degree --> 0.698131700797601 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_a = (S_c-S_b*cos(∠A))/cos(∠B) --> (20-14*cos(0.5235987755982))/cos(0.698131700797601)

Evaluating ... ...

S_a = 10.2809235387845

STEP 3: Convert Result to Output's Unit

10.2809235387845 Meter --> No Conversion Required

FINAL ANSWER

10.2809235387845 ≈ 10.28092 Meter <-- Side A of Triangle

What is a Triangle?

The Triangle is the 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.
