|
Answer» If u draw the height which the line perpendicular from the vertex to base it divides the 120 degree angle into 2 equal angles. And Also this perpendicular bisector bisect the base into equal parts. So u get two 30 -60 -90 triangleswhere side opp the 60 degree angle = 9also by the formula for this special trianglelength of side opp 60degree angle= x√3 9 = x*√39/√3 = x3√3 = xalso side opp the 30 degree angle = altitude= x = 3√3 thanks but can u do it |
