Answer» -step EXPLANATION:In triangle ABC , AB is the distance between WALL and foot of ladder CB is length of ladder and CA is height of wall.let AB be the distance between the foot of the ladder away from the wall. AB= 9.5mCB be the length of the ladder CB= xmlength of ladder is ,cos 60°= BASE HYPOTENUSE 1 2 = 9.5 X x = 2× 9.5 x = 19m. Therefore, length of the ladder is 19m .Note:please draw the diagram. |
