Question 1196476
Donald's school is due west of his house and due south of his friend Scarlett's house. The distance between the school and Scarlett's house is 3 kilometres and the straight-line distance between Donald's house and Scarlett's house is 6 kilometres. How far is Donald's house from school? If necessary, round to the nearest tenth.
<pre>The other person's WRONG! A distance he gave you is the same distance he claims is being sought.
Having said that, the distance between Donald's and Scarlett's houses is: {{{matrix(1,3, sqrt(6^2 - 3^2), "=", sqrt(27))}}}. 
Calculate and round that!
