Question

Can somebody help me please??

Answer 1

Answer:

1. z=140

2. z=130

3. z=145

4. z=180

5. z=155

6. z=120

Step-by-step explanation:

1. z+40=180 so you should subtract 40 from both sides of the equation to get 180-40=140, meaning that z=140

2. 50+z=180 so you should subtract 50 from both sides of the equation to get 180-50=130, meaning that z=130

3. subtract 35 from both sides of the equation to get 180-35=145, meaning that z=145

4. You can just solve this equation as 90+90=180, meaning that z=180

5. subtract 25 from both sides of the equation to get 180-25=155, meaning that z=155

6. subtract 60 from both sides of the equation to get 180-60=120, meaning that z=120
