What is the answer to this question?

130 degrees

Step-by-step explanation:

Remember to use 180 degrees, you subtract 180 from 50, to get angle 2, which is 130.

Like angle 1 would be; 180-60= 120

angle 3 would be; 180-70= 110

If it tells you to find the other side of the angles, (ex. opposite to 50degrees & angle 2) ; you would use 360degrees, which means the opposite side is also equal to 180, because 180 is *half* of 360degrees

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
