given:
11.5 cm
8.9 cm
to find:
the unknown value "x"
solution:
we'll have to use pythagoras theorem.
unknown value is x
[tex] {c}^{2} = {b}^{2} - {a}^{2} [/tex]
[tex] {x}^{2} = {11.5 }^{2} - {8.9}^{2} [/tex]
[tex] {x}^{2} = 53.04[/tex]
[tex]x = \sqrt{53.04} [/tex]
[tex]x = 7.282856582[/tex]
[tex]x = 7.3 \: cm[/tex]
