Question

Can anybody help me with this

Answer 1

c ≈ 9.1 m

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

c² = 4.1² + 8.1² = 16.81 + 65.61 = 82.42 ( take square root of both sides )

c =
`√(82.42 )` ≈ 9.1 m ( to the nearest tenth )
