Chapter 9, Problem 8RP

To determine

To find:The length of the altitude in the given isosceles triangle

Answer to Problem 8RP

The length of the altitude in the given isosceles triangle is $7.4$

Explanation of Solution

Given information:The sides of the triangle are $6$ , $8$ and $8$

Calculation:We first of all draw an altitude from the vertex of the isosceles triangle. Thus, we then apply Pythagoras theorem to it, and we get

  $3^2+x^2=8^2$

Where x is the length of the altitude. Thus, we get

  $x=\sqrt{55}=7.42$
