Question

a right triangle has legs of lengths 6 and 2, what is the length of the hypotenuse to the nearest tenth

Answer 1

Answer:

6.3

Step-by-step explanation:

Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.

We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.

To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.

Answer 2

Answer:

6.3

Step-by-step explanation:

$6^{2} + 2^{2} = x^{2}$

40 = $x^{2}$

$\sqrt{40} = \sqrt{x^{2} }$

x = 6.3
