Question

What is the value of n in the figure below?

Answer 1

n = 3.9

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

n² = 1.5² + 3.6² = 2.25 + 12.96 = 15.21 ( take the square root of both sides )

n =
`√(15.21)` = 3.9
