Question

In DEF, D ≈ E ≈ F. Find mD.
A. 15
B. 30
C. 60
D. 90

Answer 1

The measure of angle D in triangle DEF, where all angles are approximately equal, is 60 degrees.

Step-by-step explanation:

The student's question is asking to find the measure of angle D (mD) in a triangle DEF where all angles are approximately equal. Since the sum of angles in any triangle is 180 degrees, and all angles are approximately equal in this case, angle D can be found by dividing 180 degrees by 3. So, the measure of angle D (mD) would be 60 degrees.
