Draw a rough sketch as directed please.
\n" ); document.write( "I don't know to draw graphs with in this box. My graphs from my applications refuse to get copied into this box
\n" ); document.write( "Start from a point A
\n" ); document.write( "Go vertically up to a point B
\n" ); document.write( "Mark this length AB = 65
\n" ); document.write( "Go horizontal from B to a point C with length BC slightly longer than AB.
\n" ); document.write( "Mark this length BC= 75
\n" ); document.write( "You started your journey at A. Went up north to B. Went east from B to C.
\n" ); document.write( "If now you join A and C, then the length CA gives the distance from your destination C to the starting point A.
\n" ); document.write( "If you look at your diagram, it is a right angled triangle with
\n" ); document.write( "angle B = 90 degrees. AC is the hypotenuse.
\n" ); document.write( "So by Pythog. theorem
\n" ); document.write( "AC^2 = AB^2 + BC^2
\n" ); document.write( "=(65)^2 + (75)^2
\n" ); document.write( "= 4225 +5625
\n" ); document.write( "=9850
\n" ); document.write( "Then AC = sqrt(9850)which is approximately 99.25 kilometers
\n" ); document.write( "Answer: The required distance is approximately 99.25 kilometers
\n" ); document.write( " \n" ); document.write( "
