|
Answer» First of all we need to know that 105 is a combination of angles, 60°and45°draw yz a line of any measureat y, draw a semicircle.keeping pointer at the right side of semicircle without changing measure, cut an arc.and thats ur 60°now we need to construct 45°we all know that it is the half of 90so keeping pointer at 60, cut an arc on the semicircle, remember not to change the measure.now keeping pointer at that arc, cut another arckeeping pointer at the two new lately contructed arc and bisect it. u'll get 90°.now bisect that 90 and u'll get 45so 45 + 60 together u'll get 105° |
