1) Given the altitude BD, let's find its measure using some trigonometric relations on the Right Triangle:

1.2) Pythagorean Theorem to find the other leg

b²=a²+c² The hypotenuse, in this case, is labeled as "b"

32²=16²+a²

1024=256+a²

1024-256=a²

768=a²

√768=√c²

a=16√3

2) Now, let's use one trigonometric relation on the Right Triangle, based on the similarity of the triangles:

ah=bc Adjusting it:

bh=ac

32h=16√3*16

32h=256√3

h=256√3/32

h=8√3 ≈ 13.85 ≈13.9

3) So the altitude BC of that triangle is approximately 13.9
