1. Using the Heron's formula, calculate the area S of the triangle ABC.
The side lengths are given.
2. Next step find the length of the altitude CH from equation = S.
3. Consider right-angled triangle AHC. In it, you know AC = 26.
In section 2 you just also found the length |CH|.
So you can find the leg |AH|.
3. Now you know |AM| (it is 16 units, half of |AB|).
You also know |AH|.
The difference |AB| minus |AH| is the length |MH| under the question.
