Supplementary angles add to 180 degrees. If A and B are both supplementary to C, the two angles must be congruent since A=B=180-C.
Answer:
1. c
2. b
3. a
4. d
5. e
6. f
Step-by-step explanation:
Answer:
y=3x-2..... i
x-y=4...... ii
x-4=y
Substituting the value of y in equation i,
x-4=3x-2
2-4=3x-x
-2=2x
x=-1.
From ii,
-1-4=y
y=-5.
x=-1, y=-5
