Answer:

x = 11

Step-by-step explanation:

c = 61

61² = 61 × 61 = 3,721

b = 60

60² = 60 × 60 = 3,600

3,721 - 3,600 = 121


√(121) = 11

x = 11

Answer:

11

Step-by-step explanation:

(next time, it would be helpful to include a picture)

If you were on the same test as I was, than that means that the triangle you're looking for is the one below.

Using the Pythagorean Theorem,

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

c = 61

61^2 = 61 X 61 = 3,721

b = 60

60^2 = 60 X 60 = 3,600

Next, we subtract:

3,721 - 3,600 = 121

√121 = 11

(x = 11 cm)

so 11 is your answer
