Answer:

Use the Theorem of Pythagoras

#h = 24.6 m#

Explanation:

The theorem states that-

In a right-angle triangle, the square of the hypotenuse is the same as the sum of the squares of the other two sides.

#c^2=a^2+b^2#

In the question, a rough, right-angled triangle is portrayed.

so

#38^2=29^2+h(height)^2#

#h^2=38^2-29^2#

#h^2=1444-841#

#h^2=603#

#h= sqrt603#

#h=24.55605832#

#h=24.6#

hope that helped !
