Answer:
8
Step-by-step explanation:
∠1 = (6x + 2)° (vertically opposite angles are equal)
15x + 10° +∠1 = 180° (co-interior angles are equal)
15x + 10° + 6x + 2° = 180°
15x + 6x + 10° + 2° = 180°
21x + 12° = 180°
21x = 180° - 12°
21x = 168°
x = 168/21
x = 8
hope u understood!
Answer: 8/9 or .8
Advice for the future, use math w a y next time for stuff like this.
Answer:
<h2>a.) reflect across x-axis</h2>
Step-by-step explanation:
The transformation described is about multiplying the vertical value by -1:
That means all vertical coordinates will change to the opposite side, but all horizontal coordinates will maintain at the same coordinate.
As a result, we'll have a reflection across the x-axis, because the y coordinates were transformed.
Therefore, the right answer is A.
