X = A/y
You divide the y from both sides
The y on the right cancels
On the left you have A/y = x
The answer would be 56/299
The triangle on the left appears to be congruent with the triangle on the right. If this observation is actually valid, then x+7 = 2x-5. 12=x Yes, I realize that this doesn't match any of the answer choices, 'tho the 4th choice is the only one that contains "12." Would you please share the instructions for this problem.
