Chapter 12, Problem 4MCQ

To determine

To find the value of the angle $m\angle 1$ .

Answer to Problem 4MCQ

The value of the angle $m\angle 1$ is $113°$ .

Explanation of Solution

Given information:

Theoppositeangle is given as $113°$ .

Concept used:

Theorem of the vertically opposite angles states that the vertically opposite angles are equal.

Using the theorem, it is concluded that vertically opposite angles are equal, so the angle $m\angle 1$ can be obtained as,

  $m\angle 1=113°$

Therefore,

The value of the angle $m\angle 1$ is $113°$ .
