Question

What is the value for x in the diagram? Rounded to the tenth

Answer 1

x ≈ 10,54 units

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 17² = 20²

x² + 289 = 400 ( subtract 289 from both sides )

x² = 111 ( take the square root of both sides )

x =
`√(111)` ≈ 10.54 ( to 2 dec. places )

Answer 2

26.2

Pythagoras theorem
