Calculation of angles in triangle
WebNov 12, 2024 · You can calculate the area of such a triangle using the trigonometry formula: Base area = 0.5 × a × b × sin (Angle γ) In this particular case, our triangular prism area calculator uses the following formula combined with the law of cosines: Area = Length × (a + b + √ ( b² + a² - (2 × b × a × cos (Angle γ)))) + a × b × sin (Angle γ) WebTriangle Calculator Step 1: Enter the values of any two angles and any one side of a triangle below which you want to solve for remaining angle and sides. Triangle calculator finds the values of remaining sides and angles by using Sine Law. Sine law states that a sinA = b sinB = c sinC a sin A = b sin B = c sin C Cosine law states that-
