Questions & Step-by-Step Solutions
In triangle DEF, if angle D = 30° and angle E = 45°, what is the measure of angle F?
Steps
Concepts
Step 1: Understand that the sum of all angles in a triangle is always 180°.
Step 2: Identify the given angles in triangle DEF. Angle D is 30° and angle E is 45°.
Step 3: Add the measures of angle D and angle E together: 30° + 45° = 75°.
Step 4: Subtract the sum of angles D and E from 180° to find angle F: 180° - 75° = 105°.
Step 5: Conclude that the measure of angle F is 105°.
