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

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

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.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
