If the whole angle (ABC) is equal to 133, we can add angles ABD and DBC to find x.
10x+13=133
Subtract 13 from both sides to get
10x=120
Divide both sides by 10 to get that x=12
We can now plug the value of x into ABD to find its measure.
7(12)+4
Simplifies to 84+4, which is 88
So angle ABD is equal to 88 degrees.

If you plug in the x and y, you get
7(1)(3)
7 x 1 x 3 = 21, so the answer is 21
Step-by-step explanation:
to my guess the rule of a reflection will be about the x-axis since only the values of y have changed
