Question

Transcribed Image Text:**Solve for \(x\) and \(y\).**
**Problem 4:**
The diagram shows a triangle with three angles labeled. The angles are:
- Top angle: \(50^\circ\)
- Bottom left angle: \(2x^\circ\)
- Bottom right angle: \(3y^\circ\)
**Problem 5:**
The diagram shows a triangle with the following angles:
- Bottom left angle: \((4x - 10)^\circ\)
- Bottom right angle: \((2x + 12)^\circ\)
- Top angle: \(4y^\circ\)
Two sides of this triangle are marked with a single hatch mark, indicating they are of equal length (an isosceles triangle).
**Problem 6:**
The diagram shows two intersecting lines forming an "X" shape with the following angles:
- Top left angle: \((7y - 3)^\circ\)
- Top right angle: \((3y + 13)^\circ\)
- Bottom angle: \((2x + 3)^\circ\)
The sides opposite these angles that form two triangles are marked with hatches indicating they are equal. In each triangle, the opposite non-segment corner angles are equal, suggesting they are vertically opposite angles.
