Angle measurement DEF=107 degrees
You must first find angle F- since it is against a flat line, we know 180=F+135. Subtract 135 from each side and we find F is 45 degrees.
Then, since a triangle’s angles must always equal 180 degrees, we subtract angles D and F from 180 to get 107 degrees.
No bc Lisa didn’t add all of the numbers together. When finding the mean you add all numbers together then divide by how many numbers you have.
