Answer to Problem 6RP

The length of side AH is 535+1196units .

Explanation of Solution

Given information:

A quadrilateral RHOA is inscribed in a circle.

Consider the figure of the quadrilateral RHOA as,

  Geometry For Enjoyment And Challenge, Chapter 16, Problem 6RP

In this quadrilateral RAO is a right angle, so apply the Pythagorean Theorem to find the value of AO as,

  (AO)2=(RO)2(AR)2(AO)2=(12)2(5)2AO=119units

Similarly, calculate the value of HO as,

  (HO)2=(RO)2(HR)2(HO)2=(12)2(2)2HO=140HO=235units

The length of side AH is calculated by using Ptolemy’s Theorem as,

  12(AH)=5(HO)+2(AO)12(AH)=5(235)+2(119)AH=535+1196units

Thus, the length of side AH is 535+1196units .
