Answer 19

@ehmuleeee still there?

Answer 20

yesss

Answer 21

if you take a peek at the "2 triangles" the smaller inside and the bigger containing it

the opposite side for the bigger is the "correspondent" to the "x" in the smaller one
using pythagorean theorem the opposite side of the bigger triangle will be
\(\bf c^2 = a^2 + b^2 \implies \sqrt{c^2-a^2} = b^2\)

Answer 22

thus the 16 units UP are really just the radius, the other line going down from it, would also be the radius and is thus 16 too, so the "c" side is really 16+16 = 32, "a" is 25.6
thus
\(\bf b = \sqrt{32^2-25.6^2} \implies 19.2\)

Answer 23

the just solve for "x"
