Answer:

[tex]4\sqrt{21}[/tex]

Step-by-step explanation:

16 is split into half to get 8. then use the pythagorean theorem to solve for the altitude.

a^2 + b^2 = c^2

8^2 + b^2 = 20^2

64 + b^2 = 400

b^2 = 336

b = [tex]\sqrt{336}[/tex]

simplify to [tex]4\sqrt{21}[/tex]

Answer:18.3

Step-by-step explanation:

16/2=8

altitude=√(20^2-8^2)

altitude=√(20x20-8x8)

altitude=√(400-64)

altitude=√(336)

altitude=18.3
