Step 1: Identify the properties of the figure. The diagram shows two parallel lines intersected by two transversals, forming an isosceles triangle. The tick marks on the two slanted sides indicate they are equal, meaning the base angles of the triangle are equal. Step 2: Use the property of alternate interior angles. The angle 2y is an alternate interior angle to the bottom-left angle of the triangle. Therefore, the bottom-left angle of the triangle is 2y. The angle 56^ is an alternate interior angle to the bottom-right angle of the triangle. Therefore, the bottom-right angle of the triangle is 56^. Step 3: Apply the property of an isosceles triangle. Since the triangle is isosceles, its base angles are equal. 2y = 56^ Step 4: Solve for y. Divide both sides by 2: y = (56^)/(2) y = 28^ The value of y is 28^. This corresponds to the first option. The final answer is 28^. That's 2 down. 3 left today — send the next one.
