Certainly! Let's break down the exercises on the worksheet:

### Bài 3:
Given a quadrilateral \(MNPQ\) with the following angles:
- \(\angle N = M + 10^\circ\)
- \(\angle P = N + 10^\circ\)
- \(\angle Q = P + 10^\circ\)

Quadrilaterals have the angle sum property, which means:
\[
\angle M + \angle N + \angle P + \angle Q = 360^\circ
\]

Using the given expressions for the angles in terms of \(M\), we can solve for each angle.

### Bài 4:
Given quadrilateral \(ABCD\) with:
- \(\angle ABC = 135^\circ\)
- \(\angle ACB = 24^\circ\)
- \(\angle ADC = 60^\circ\)

You need to find \(\angle DAC\). Use properties of triangles and supplementary angles based on the given conditions.

### Bài 5:
Given quadrilateral \(ABCD\) with:
- \(\angle D = 72^\circ\)
- \(\angle C = 68^\circ\)

The angle bisectors of \(\angle A\) and \(\angle B\) intersect at \(E\). You are tasked with finding the measure of \(\angle AEB\).

Explore the properties of angle bisectors and supplementary angles to find \(\angle AEB\).
