Answer:
x = 21
Step-by-step explanation:
<u>Step 1: Make an expression</u>
Since they are supplements, that means that they add up to 180 degrees.
3x + 6 + 5x + 6 = 180
<u>Step 2: Combine like terms</u>
3x + 6 + 5x + 6 = 180
(3x + 5x) + (6 + 6) = 180
8x + 12 = 180
<u>Step 3: Subtract 12 from both sides</u>
8x + 12 - 12 = 180 - 12
8x = 168
<u>Step 4: Divide both sides by 8</u>
8x / 8 = 168 / 8
x = 21
Answer: x = 21
Answer:
Thus, option A is correct.
Explanation:
<u>match the proportions</u>
<u>set up a equation:</u>
*Hint: When a figure is reflective about the y-axis, the rule would be (-x, y)
So as you can see, all the points of the figure changed from a negative x to a positive one but kept the same y value. And then after the translation up by 6 units, the final rule would be (-x, y + 6) and if you were to plug in the points, you would see they would end up as the image.
The answer to this question would be:
B.) Reflection about the y-axis followed by translation up by 6 units.
Y=112 because of vertical angles or if you subtract 68 from 180 to get it.
Answer:
B.
Step-by-step explanation:
That's like the only answer that makes sense.
