In triangle abc ac=12cm bc=6cm and ab=6root 3 find the measure of angle b |
| Answer» Triangle ABC Assuming ABC is a right angled triangleBy Pythagoras theorem we getAC*2=BC*2+AB*2 12*2=6*2+6√3*2144=36+(36)3144=36+108144=144Hence it satisfies Pythagoras theoremSo our assumption is right ∆Also angle b=90° | |
