It's dilation by a scale factor of 4 followed by reflection on the y-axis because first, the difference between each triangle is 4. That's the scale factor. Then you find reflection. It's on the y-axis because it flipped sideways. If it was x-axis, it would've reflected down into the negatives. Confused? Let me know

Answer:

angle 1 =135

Step-by-step explanation:

it is 180 degrees total. We know that there are two angles that have a ratio to 3:1. So, assign x to 2. Since 1 = 3x, we do 3x+x =180

4x=180

x=45 or angle 2

180-45=135 or angle 1

Multiply angle 2 by 3 to check if its correct
