Answer: x=24
Explanation:
1. We know that both of the angles together are equal to 180 because they are alternate exterior angles; therefore, we place them in an equation equal to 180.
x-17+7x+5=180
2. Next, we combine like terms.
8x-12=180
3. Then, we add 12 on both sides, which cancels the 12 on the left side and makes the right side 192.
8x=192
4. Finally, we divide by 8 on both sides and get the answer of 24.
x=192/8 which is also x=24
