Triangle LPT is an obtuse scalene triangle. if angle P is the obtuse angle in triangle LPT, which of the following is not a valid conclusion?
A) m<L+m<T<m<P
B) m<P+m<T<90 degrees
C) m<L+m<T<90 degrees
D)m<L+m<P+m<T=180 degrees

I'd say A

Can you give us an explanation?

well I thought like this, P must be the highest angle cause it is an obtuse angle, and inside a triangle the sum of all angles must be 180 then A is the only one that fits it
