1) blueville is directly east of greentown, and yellowsburg is

141 miles directly north of blueville. if greentown is 158 miles from yellowsburg, how far is blueville from greentown (in miles)?

2) a high school basketball court measures 84 feet by 50 feet. if a coach has her players sprint diagonally across the court, how far do they run (in feet)?

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
