Question

In centimeters, what is the unknown length in this right triangle

Answer 1

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  

$\sqrt{121}$ = 11

x = 11

Answer 2

Answer:

11

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
