In the given figure, if LK = 63 , find MK, ML, KN, MN and the perimeter of ◻MNKL.
Please read the guide .
Please answer the question in detail
Solution::
In △ LKM ,
tan30∘=MLLK
⇒ML=63×13=6
cos30∘=LKMK
⇒MK=LKcos30∘=6332=12
NK=MK (Side opposite to equal angles )
∴NK=12
In△MKN
sin45∘=NKMN
12=12MN
MN=122
Perimeter of ◻MNKL =MN+NK+Lk+ML
perimeter =122+12+63+6
=18+6(22+3) unit {if cm then cm}
