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.

step-by-step explanation:

it's the only multiple of both and the least

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
