... the one they ask for when a triangle needs solving!In your solving toolbox (along with your pen, paper and calculator) you have these 3 equations:1. Angles Add to 180°: A + B + C = 180° When you know two angles you can find the third. 2. Law of Sines (the Sine Rule...
which should still be on our calculator from the last calculation. sin B = (sin(49°) × 5) / 5.298... sin B = 0.7122... B = sin-1(0.7122...) B = 45.4° to one decimal place Now we find angle C, which is easy using 'angles of a triangle add to 180°': C = 180...
Once you understand the Law of Sines and the Law of Cosines, you can use these formulas to solve any triangle that has at least three pieces of information. To solve a triangle means that you find the measure of each angle and the length of each side. Depending on what information you ...
Example 9: Related Rates Triangle A triangle has two sides: a = 2 cm and b = 3 cm. How fast is the third side c increasing when the angle α between the given sides is 60° and is expanding at the rate of 3° per second? Example 9: Related rates triangle John Ray Cuevas Solutio...

Yes, the law of cosines can be used to solve for theta in a triangle with any type of angle. This law states that the square of one side of a triangle is equal to the sum of the squares of the other two sides minus twice the product of those two sides and the cosine of the inc...
The other possible answer for L is 149.9°. But that is impossible because we already have M = 125° and a triangle can't have two angles greater than 90°.Conclusion:When solving a "Side, Side, Angle" triangle we start with the Law of Sines, but need to check if there is another...
