To solve for $x$, $y$, and $z$ in the given rhombus, we need to utilize the properties of a rhombus, especially the fact that opposite angles are equal.

Key properties of a rhombus:

1. Opposite angles are equal.
2. The sum of the angles in any quadrilateral is $360^\circ$.

Given the following information:

• One angle is $71^\circ$.
• Another angle is $(-6y + 1)^\circ$.
• A third angle is $(-4z + 5)^\circ$.
• The fourth angle is $(-x - 8)^\circ$.

Step-by-step solution:

Step 1: Opposite angles are equal.

• The angle opposite the $71^\circ$ angle will also be $71^\circ$.
• Therefore, we can set: $-4z + 5 = 71$ Solve for $z$: $-4z = 71 - 5$ $-4z = 66$ $z = \frac{-66}{-4} = 16.5$

Step 2: Sum of angles in a rhombus is $360^\circ$.

The sum of all angles is: $71 + (-x - 8) + (-6y + 1) + 71 = 360$ Simplify the equation: $71 + (-x - 8) + (-6y + 1) + 71 = 360$ $142 - x - 8 - 6y + 1 = 360$ $135 - x - 6y = 360$ $-x - 6y = 360 - 135$ $-x - 6y = 225$

Step 3: Solve for $x$ and $y$.

We also know that opposite angles are equal: $-6y + 1 = -x - 8$ Simplify: $-6y + 1 = -x - 8$ $-6y + x = -9$

Now we have a system of equations:

1. $-x - 6y = 225$
2. $-6y + x = -9$

We can solve this system of equations by substitution or elimination. Let's solve it:

From equation (2), solve for $x$: $x = 6y - 9$

Substitute this into equation (1): $-(6y - 9) - 6y = 225$ Simplify: $-6y + 9 - 6y = 225$ $-12y + 9 = 225$ $-12y = 225 - 9$ $-12y = 216$ $y = \frac{216}{-12} = -18$

Step 4: Solve for $x$.

Now, substitute $y = -18$ back into $x = 6y - 9$: $x = 6(-18) - 9$ $x = -108 - 9 = -117$

Final answers:

• $x = -117$
• $y = -18$
• $z = 16.5$
