Answer 3

I also got the same message, with a little dog biting a pencil and ripping up homework paper.

Answer 4

I can also confirm that the message appears when you click on the link

Answer 5

How about now? :) @mathstudent55 @jtryon

Answer 6

Here's a very, very handy theorem.
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Answer 7

Angle DFG is an exterior angle of this triangle.
The remote interior angles are the interior angles that are far from angle DFG.

Answer 8

Were you able to answer the question?

Answer 9

I think it's 66? @mathstudent55

Answer 10

@mathstudent55

Answer 11

Did you read any of my explanation above?

Answer 12

It's not 66.
66 is the measure of angle EFD.
You need the measure of angle DFG.
