Answer:
x = 119
z = 28
Explanation:
To find x: Because of same-side exterior angles, you can add x and 61 together to find 180 degrees.
x + 61 = 180
Subtraction: x = 119
To find z: Use given quantities, not found variables for most accurate answer. Because of opposite exterior angles, you can equal them to each other.
61 = 5z - 79
Addition: 140 = 5z
Division: 140/5 = 5z/5
Final Answer = 28 = z
