Answer:
b
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
If you mean they are the sides lengths,
33^2+ 56^2 != 66^2
3136 != 4356
You can see that the two small angles are close to the 43 degree angle they are both acute while the other is obtuse. Now i'm only in Tenth grade and i read certain letters backwards so i may mix you up but i'ma try.
B should be a 40 degree angle or lower i dont know i dont have my protractor when i need it.
i cant give you the other two cause its too blury to read
