Geometry length of triangle sides
Web... 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. The angles always add to 180°: A + B + C = 180° When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) WebSum of the measures of two angles = 75° + 60° = 135°. Using the properties of a triangle, we know that the sum of all three angles of triangle = 180°. Therefore, the measure of the third angle = 180° - 135° …
