Answer:
B. L & N
Explanation:
Hello!
The missing angle in Triangle L can be determined by subtracting 90° and 30° from 180°, which gets us 60°.
The other triangle that has 90° and 60°, N, has a missing angle of 30°.
Both triangles L and N have the same angles, thus following the Angle-Angle criteria.
The other two triangles, M and O, have the missing angles of 35° and 45°, respectively.
Remember: The sum of angles in a triangle is 180°.
