Work out the value of x as a decimal (oh my god, me, this is for tomorrow and i can't do it)

Check the picture below.

x ≈ 7.42 ( to 2 dec. places )

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

x² + 3² = 8²

x² + 9 = 64 ( subtract 9 from both sides )

x² = 55 ( take the square root of both sides )

x = ≈ 7.42
