Answer:

Pythagoras theorem states that:

In a right-angled triangle,the hypotenuse , altitude and base are related as:

$(Hypotenuse)^2=(Base)^2+(Altitude)^2$

In this question:

Hypotenuse = 20 units

Base = 12 units

Altitude = w = ?

By Pythagoras theorem:

$20^{2}=12^{2}+w^2\\w=\sqrt{400-144}=\sqrt{256}\\w=16\ units$

Hence w = 16 units.
