Answer to Problem 5PS

The possible values of x are 7611or 9211 .

Explanation of Solution

Given information:

The coordinates of the vertices of the triangle are (2,6),(4,17),and(x,11) . The area of the triangle is 42 .

The area of ΔTRY is calculated as,

  A=12|(2)(17)+4(11)+6x(2)(11)4(6)17x|42=12|(2)(17)+4(11)+6x(2)(11)4(6)17x|84=|811x|x=7611or 9211

Thus, the possible values of x are 7611or 9211 .
