Question

What is GM?

I need the answer pleaseee help me

Answer 1

Answer: 18

Explanation:

`\triangle HJK \cong \triangle HLK` by HL. Therefore,
`JK=2` by CPCTC.

Using the segment addition postulate,
`GK=9`.

Furthermore,
`\triangle HGK \cong \triangle HMK` by HL. This means that
`MK=9` by CPCTC.

Using the segment addition postulate again,
`GM=9+9=18`.
