Angles 1 and 2 are a.) supplementary. This means that b.) the measure of each when added will be equal to 180 degrees. We can see this because they are both "flat" on a line next to each other.
The answer is 2x/x-1 because it means opposite
4+2 = 6 a a a a + a a = a a a a a a
2+4 = 6 a a + a a a a= a a a a a a
Tommy is correct They are both equal to 6
This is the overall final answer in fraction and decimal form.
