In \triangle JKL,△JKL, \angle J \cong \angle L,∠J≅∠L, LJ = 17LJ=17 and KL = 10KL=10. Find the length of JK.JK.

Answer 1

It's a isosceles right angled triangle

• LJ=17
• KL=10

`\\ \sf{:}\Rrightarrow JK^2=17^2+10^2`

`\\ \sf{:}\Rrightarrow JK^2=289+100`

`\\ \sf{:}\Rrightarrow JK^2=389`

`\\ \sf{:}\Rrightarrow JK=19.72`
