Please answer this question..... very urgent. Q17. In the figure below, AL is perpendicular to BC and CM is perpendicular to AB. If CL = AL = 28 L, find MC/ AM (A) 2 (B) 3 (C) 4 (D) Cannot be determined Share with your friends Share 0 Lovina Kansal answered this Dear student Let BL=1Then CL=AL=2 ∵AL=CL=2BLIn △ALB by pythagoras theorem.AB=AL2+BL2=22+12=5and In ALC by pythagoras theorem.AC=AL2+CL2=22+22=8=22Let AM=x.ThenIn AMC by pythagoras theorem.CM=AC2-AM2=222-x2=8-x2In △ALB and △MCB∠ALB=∠CMB [each 90°]∠B=∠B [Common]So, △ALB~△CMB [By AA criteria]So, ALCM=LBMB=ABCB⇒ALCM=ABCB⇒AB×CM=CB×AL⇒5×8-x2=3×2⇒58-x2=36⇒8-x2=365⇒8-x2=7.2x2=0.8So, MCAM=8-x2x=8-0.80.8=7.20.8=9=3 Regards 0 View Full Answer
