Find the length of the missing leg.

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= cm

x =

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 =

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
