X=22. The supplementary angle is 90°, so the 66° angle, plus (x+2) has to add up to 90° too.
Answer:
Step-by-step explanation:
If
a = 3+ 10 b
It can be written as
b = (a - 3)/10
But
c = 2 + 5b
Now inserting the value of b from above equation
We get
c = 2 + 5 (a - 3)/ 10
c = 2 + ( a - 3 )/2
2c = 4 + a - 3
a = 2c - 1
You would move each coordinate 6 left and 1 up
A(2,5)
B(0,2)
C(-1,3)
