Question

Find the length of the missing leg.

Answer 1

Answer:

Step-by-step explanation:

using formula

a^2+b^2=c^2

x^2+4^2=8^2

x^2+16=64

x^2=64-16

x=$\sqrt{48}$ cm

Answer 2

Answer:

x = $\sqrt{48}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 4² = 8²

x² + 16 = 64 ( subtract 16 from both sides )

x² = 48 ( take the square root of both sides )

x = $\sqrt{48}$
