Question

An aircraft flies equal distance south east and then south west to finish 120km due south of its starting point. How long is each part of its journey?

​

Answer 1

You are dealing with an isosceles right triangle where the hypotenuse is 120 km long. Calculate the length of the legs.

Answer 2

Answer:

84.89

Step-by-step explanation

Using pythagoras theorem,

⇒ 120 = x^2 + x^2

⇒ 120 = 2x^2

⇒ 120 = x√2

⇒ x = 120/√2

⇒ x = 84.89 km
