Question

Some one please help me i’m so stuck it’s urgent

Answer 1

We already know the values of IL, JL and JK.

We can use the value of IL and JL to find IJ. Substract JL from IL to find IJ.

`\begin{gathered} IL-JL=IJ \\ 49-31=IJ \\ IJ=18 \end{gathered}`

Now, we can add JK to IJ to find IK:

`\begin{gathered} IJ+JK=IK \\ 18+12=IK \\ IK=30 \end{gathered}`

IK is 30.
