Question

ΔLPT is an obtuse scalene triangle. If ∠P is
the obtuse angle in ΔLPT, which of the
following is not a valid conclusion?
A m∠L + m∠T < m∠P
B m∠P + m∠T < 90°
C m∠L + m∠T < 90°
D m∠L + m∠P + m∠T = 180°

Answer 1

b since p is an obtuse so it must be bigger than 90 degrees, so p +t must >90 degrees, b is wrong

Answer 2

thank you
