Can someone please tell me if these triangles are similar or not, and why.

Answer:
No they are not similar.
Step-by-step explanation:
Because their angles are not the same. 1st triangle: 42-48-90 2nd triangle:58-32-90
Answer:
No, they are not similar.
Step-by-step explanation:
All the angles in a triangle add up to 180°. In both triangles, we already know two of the angles - 42° and 90° in one, 58° and 90° in the other.
Let's see if they match.
180 - 90 - 42 = 48
That's 48, not 58...
Let's check again with the other triangle.
180 - 90 - 58 = 32
48 does not equal 58.
32 does not equal 42.
Therefore, the two triangles are not similar.
