Chapter 12.4, Problem 32E

To determine

To Find: The expression representing the possible angle measure of a triangle in terms of $x.$

Answer to Problem 32E

  $0.75xand0.25x.$

Explanation of Solution

Given: The measure of the exterior angle of the isosceles triangle is $x^{°}$ .

The measure of the exterior angle is $x^{°}$ .

Then

Measure of interior angle that is supplementary with the angle is ${180}^{°}-x.$

Now

We know that the exterior angle is the sum of the two opposite interior angles.

So let us assume that the measure of other two interior angles are $0.75xand0.25x.$
