1. **Problem:** Find the unknown angle \(\angle U\) in kite \(WVUT\) given \(\angle V = 74^\circ\) and \(\angle T = 96^\circ\). 2. **Properties of kites:** The sum of interior angles in any quadrilateral is \(360^\circ\). In a kite, two pairs of adjacent sides are equal, and one pair of opposite angles are equal (angles between unequal sides). 3. **Formula:** \(\angle W + \angle V + \angle T + \angle U = 360^\circ\). 4. **Calculation:** Given \(\angle V = 74^\circ\), \(\angle T = 96^\circ\), and \(\angle W = \angle U\) (since they are opposite angles between equal sides in kite), let \(\angle W = \angle U = x\). 5. Write equation: $$x + 74 + 96 + x = 360$$ 6. Simplify: $$2x + 170 = 360$$ 7. Solve for \(x\): $$2x = 360 - 170 = 190$$ $$x = \frac{190}{2} = 95$$ 8. **Answer:** \(\angle U = 95^\circ\). This uses the property that in a kite, the angles between the pairs of equal sides are equal, and the sum of all angles is 360 degrees.
