Pythagorean Theorem is a[tex] a^{2} + b^{2} = c^{2} [/tex] . Plug in the given values: 3^2 + b^2 = 9^2
9+b^2 = 81
b^2 = 81-9
b^2 = 72
Square root both sides:
b = [tex] \sqrt{72} [/tex]
Simplify [tex] \sqrt{72} [/tex] = [tex]6 \sqrt{2} [/tex]
9+b^2 = 81
b^2 = 81-9
b^2 = 72
Square root both sides:
b = [tex] \sqrt{72} [/tex]
Simplify [tex] \sqrt{72} [/tex] = [tex]6 \sqrt{2} [/tex]
