Chapter 13.8, Problem 6CE

To determine

To find:The missing coordinates without introducing any new letters.

Answer to Problem 6CE

The missing coordinate is $P\left(b,0\right)$ .

Explanation of Solution

Given information: In graph, Rt. ΔTOP is isosceles triangle.

Since, point Plies on x-axis.

So, y-coordinateof P will 0.

In isosceles triangle, two sides are equal.

In right isosceles triangle, sides adjacent to right angle are equal.

So, sides OP and OT are equal

Length of OP is its x-coordinate and length of OT is its y-coordinate.

Since,

  $OP=OT$

So, x-coordinate of OP is b.

Hence, the missing coordinate is $P\left(b,0\right)$ .
