Answer:
The triangles are similar
Explanation:
You first flip the first triangle so the hypotenuse is facing the bottom right like the second triangle and the 49 degrees would be matching the same side as the picture would depict
You can then use the equaation 43 + 49 + x = 180 to solve for the missing angle in the second right triangle.
92 + x = 180
x = 88
The degrees match up, you then have to compare the sides.
You can first check the ratios between the same sides of the different triangles.
2.8 : 8.4
4 : 12
3.1 : 9.3
all of these ratios would be simplified to a 1:3 ration, meaning all the sides are proportional, making the triangles similar.
