Question

A ship goes 72 km due north and then 65 km due east. How far is the ship in a straight line from
the starting point?​

Answer 1

97km from starting point.

Using Pythagoras Theorem,

$SE^2 = SN^2 + NE^2 \\ SE = \sqrt{ {72}^{2} + {65}^{2} } \\ SE = \sqrt{ 5184 + 4225 } \\ SE = \sqrt{ 9409 } = 97$

Answer 2

Answer:

97km from starting point.

Using Pythagoras Theorem,

Step-by-step explanation:

SE²=SN²+NE²

SE√72²+65²

SE=97km
