Answer:
The given argument is valid by the law of detachment
Step-by-step explanation:
Law of Detachment states that if the following two statements are true:
(1) If a , then b .
(2) a
Then we can say a third true statement:
(3) b.
Given:
1) If a triangle has an angle with a measure more than 90°, then the triangle is an obtuse triangle.
2) The measure of an angle in △ABC is 110°.
Let the statement a be "If a triangle has an angle with a measure more than 90°" , and b be the statement "the triangle is an obtuse triangle."
then, (1) and (2) can be written as:
1) If a , then b.
2) a
so, by the Law of Detachment, we can say that b is true i.e,
is an obtuse triangle.
