Answer:

m < X + m < Y < 90

Step-by-step explanation:

For the triangle  XYZ, m∠Z > m∠X + m∠Y we see that because the total internal angles of a triangle is 180,m∠X + m∠Y < 90° is a true assertion

Option C is correct

What must be true about triangle XYZ?

Generally, A triangle's major feature is its total internal angles as 180

Therefore

if m∠Z > m∠X + m∠Y this means that m<z must be greater than 90 degrees

This goes to show us that

m<X + m<Y  < 90  because as we earlier mentioned the total internal angles of a triangle is 180 .

In conclusion, For the triangle XYZ

m∠X + m∠Y < 90° is a true assertion
