Answer:
80*
80*
75*
120*
Step-by-step explanation:
both angle 1 and 2 for the first image have the same value as the other angle of 80* because it is a set of parallel lines and one line going through it.
1 on the next set of images is 75* because is is an alternate exterior angle.
2 of the last set of images is 120* because it is same side interior angles.
The x becomes negative because the negative sign at the start of the parenthesis distributes to everything inside parenthesis so x becomes -x and the double negative becomes +6 so that is why
The answer is exponential decay
