Identify the hypothesis of the following conditional statement: If an angle measures 120°, then it's an obtuse angle. Question 12 options: A) An angle doesn't measure 120°. B) It isn't an obtuse angle. C) It's an obtuse angle. D) An angle measures 120°.

Answer: Option D.

Step-by-step explanation:

The "skeleton" of a logic statement is usually:

If "something true" then "this is also true"

Where the correct way to write this is:

"if hypothesis" then "conclusion".

Or

"Conclusion" only if "hypothesis"

There are other ways to write a logical statement, but this gives a general idea.

The hypothesis is the part of a logical statement that gives the premise on which the conclusion is based.

Now, in our statement we have:

If an angle measures 120°, then it's an obtuse angle.

Here the premise, the thing that needs to be true "first" in order to go to the conclusion, is "an angle measures 120°"

Then the correct option is D.
