Question

Given a right triangle with a = 3 cm and b = 7 cm, what is the length of c? Your answer:

Answer 1

The length of c
`=√(58)` cm.

Explanation:

Considering the figure of right triangle attache below.

For a right angled triangle with sides
`a` and
`b`, the hypotenuse
`c` is defined as

`c=√(a^2+b^2)`

• 
  `a=3`

• 
  `b=7`

`c=√(3^2+7^2)`

`c=√(58)` cm

Therefore, the length of c
`=√(58)` cm.
