Triangle ABC and Triangle XYZ are similar. If angle A=30 and angle B=45, what can you conclude?

A. Triangle XYZ is acute.

B. Triangle XYZ is isosceles.

C. Triangle XYZ is right.

D. Triangle XYZ is obtuse.

The given angles sum to less than 90°, so the remaining angle must be more than 90°. (The total of all angles is 180°.) Triangle ABC has an angle greater than 90°, so is obtuse. Since the triangles are similar, their corresponding angles are congruent. Hence ...

.. D. Triangle XYZ is obtuse.
