Answer The another right angle is ∠ A F D Explanation Given information : It is given that ∠ A F B is a right angle in the figure below Given that ∠ A F B is a right angle and the sum of angles on a straight line is 180 ° . So, we get ∠ A F B + ∠ A F D = 180 ° 90 ° + ∠ A F D = 180 ° ∠ A F D = 180 ° − 90 ° = 90 ° Therefore, the another right angle is ∠ A F D

Expert Solution & Answer

Answer to Problem 7WE

The another right angle is ∠AFD

Explanation of Solution

Given information : It is given that ∠AFB is a right angle in the figure below

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 2.4, Problem 7WE

Given that ∠AFB is a right angle and the sum of angles on a straight line is 180° .

So, we get

∠AFB+∠AFD=180°90°+∠AFD=180°∠AFD=180°−90°=90°

Therefore, the another right angle is ∠AFD
