Answer:

For better understanding of the solution, see the attached figure of the problem :

1). From the diagram, since Yellowsburg is directly north of Blueville therefore AB will be perpendicular to BC and ∠ABC = 90

Now, In ΔABC, using Pythagoras theorem

AC² = AB² + BC²

158² = 141² + BC²

BC² = 158² - 141²

BC² = 5083

⇒ BC = 71.3 miles

Hence, Blueville is 71.3 miles away from Greentown.

2). The basketball court is in shape of rectangle whose dimensions are given by :

Length = 84 feet and Breadth = 50 feet

Since, Each angle of rectangle is 90 hence by using Pythagoras theorem in ΔPQR :

PR² = PQ² + QR²

PR² = 84² + 50²

PR² = 9556

PR = 97.75 feet

Hence, If a coach has her players sprint diagonally across the court, they need to run 97.75 feet
