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
