The rate of change is +2 or 2 over 1 or 2/1
Less than 90° = acute
more than 90° = obtuse
equal to 180° = straight
more than 360° = reflex
The answer is 21.

Answer:it will probably be true
Step-by-step explanation:
It would probably be true.
Since the angles add to 180°, angle F is 72°.
Using the law of sines,
DF/sin72° = 24/sin45°
x = 32.28
So, did you just guess at A?
This is just an answer from another website, but it should still work.
