Chapter 8.2, Problem 2CE

To determine

To Find: Find the correct equation for the right triangle shown in figure.

Answer to Problem 2CE

The correct equation is $t^2=r^2+s^2$

Explanation of Solution

Given information: We have given a figure as shown below

  

From Pythagorean Theorem we know that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.

The given triangle is right triangle.

Therefore,

  $t^2=r^2+s^2$

It can also be written as $s^2=t^2-r^2$

The correct equation is option (d)
