Using the Pythagorean Theorem:

x^2 = 61^2 - 60^2

x^2 = 3721 - 3600

x^2 = 121

x = SQRT(121)

x = 11 cm.

Hey!

You have to use the Pythagorean Theorem.

a² + b² = c² is the same as: c² - b² = a²

[tex] c = 61 \\ 61^{2} = 61 \times 61 = 3,721 [/tex]

[tex] b = 60 \\ 60^{2} = 60 \times 60 = 3,600 [/tex]

Subtract:

[tex] 3,721 - 3,600 = 121 [/tex]

√121 = 11
