There are 3 interior angles.
The answer will be A due to them being on opposite sides with the triangle having adjacent measures so both of those angles given provide the same measure
Y=x-7 this is because you subtracted the x to both sides. Since y is a negative, you divide by -1 causing the -x to turn positive and the positive seven to be negative seven.
Answer:
100000000
Step-by-step explanation:
6 times 10 to the 8th is 600,000,000
5 times 10 to the 7th is 500,000,000
600,000,000-500,000,000=100,000,000
If two positive angles have a sum of 180 degrees, they are called supplementary angles.
