Answer:
None of the above
Step-by-step explanation:
The figure3 shows 1 side and 1 angle of one triangle congruent to 1 side and 1 angle of the other triangle. We are not shown anything else, so the answer is:
None of the above
and you can't prove the triangles congruent.

Answer:
x = 12
Step-by-step explanation:
Solve for x:
5 (x - 6) = 2(x + 3)
Expand out terms of the left hand side:
5x - 30 = 2(x + 3)
Expand out terms of the right hand side:
5x - 30 = 2x + 6
Subtract 2x from both sides:
(5x - 2x) - 30 = (2x - 2x) + 6
5x - 2x = 3x:
3x - 30 = (2x - 2x) + 6
2x - 2x = 0:
3x - 30 = 6
Add 30 to both sides:
3x + (30 - 30) = 30 + 6
30 - 30 = 0:
3x = 6 + 30
6 + 30 = 36:
3x = 36
Divide both sides of 3x = 36 by 3:




x = 12
