Which statement is true about this argument? Premises: If a triangle has an angle that measures 150°, then it is an obtuse triangle. △JKL△JKL is an obtuse triangle. Conclusion: △JKL△JKL has an angle that measures 151°. The argument is not valid because the conclusion does not follow from the premises. The argument is valid by the law of detachment. The argument is valid by the law of syllogism. The argument is not valid because the premises are not true.
