Hi,
Concept: The given problem is based on 3 Dimensional Geometry.
Consider three axes in defined space be x, y & z in their positive directions then - x , -y & -z be their negative axes.
The coordinate of given point A(x1, y1, z1) = (1, -3, 4)
If we take the reflection of point A about xz - plane x and z coordinates will remain same and y-coordinate will give its reflection. It means the value of y-coordinate will be changed which will be +ve 3.
Hence, the reflection of A(1, -3, 4) will be A'(x2, y2,z2= (1, 3, 4).
Hello there!
Your answer would be
CAT (top line) = DBU (bottom line)
CAT (bottom line) = BZS (top line)
Hope I helped!
Let me know if you need anything else!

Answer:
AOC = 20 degrees
Step-by-step explanation:
We know that FOB is 70 degrees, and COF is 90 degrees. So just add 70+90 and get 160 degrees. Then you subtract that from AOB which is 20 degrees.
Explanation:
5(y+3)-11=-y-6 Given
5(y+3)=-y+5 . . . . addition property of equality (11 is added)
5y+15=y+5 . . . . . distributive property (5 is distributed)
5y=-y-10 . . . . . . . addition property of equality (-15 is added)
6y=-10 . . . . . . . . . addition property of equality (y is added)
y=-5/3 Division Property of Equality/Reduce
