The ans is 18m. By Pythagoras theorem you can find the hypotenuse that is 13m, then add 13 and 5m to get the height

Let A’CB be the tree before it broken at the point C and let the top A’ touches the ground at A after it broke. Then ΔABC is a right angled triangle, at B.
AB = 12 m and BC = 5 m
Using Pythagoras theorem,
In ΔABC
(AC)²=(AB)²+(BC)²
(AC)²=(12)²+(5)²
(AC)²=144+25
(AC)²=169
AC = √169
AC= 13 m
Hence, the total height of the tree(A’B) = A’C + CB = 13 + 5 = 18 m.
