J = L - 7

K = 2L - 21

L = L

Sum of the interior angles of any triangle equal 180 . Thus ;

`L + K + J = 180`

`L + (2L - 21) + (L - 7) = 180 \\`

`4L - 28 = 180`

Add sides 28

`4L - 28 + 28 = 180 + 28`

`4L = 208`

Divide sides by 4

`(4)/(4) L = (208)/(4) \\`

`L = 52`

So :

`J = L - 7`

`J = 52 - 7`

`J = 45`

And :

`K = 2 L - 21`

`K = 2(52) - 21`

`K = 104 - 21`

`K = 83`

Done...
