Question

In the adjoining figure MKL - 30",
MNK - 45° if ML - 3 then find
MK and MN


​

Answer 1

Answer:

In △LKM

tan30∘=LKML⇒ML=3×31=1

cos30∘=MKLK⇒MK=cos30∘LK=233=2

NK=MK (Side opposite to equal angles )

∴NK=2

In△MKN

sin45∘=MNNK

NK=22

Perimeter of □MNKL =MN+NK+NL+ML

⇒Perimeter =22+2+3+1

=(22+

Answer 2
