Two lines meet at a point that is also the endpoint of a ray. Set up and solve an equation to find the value of w.

w=35

Step-by-step explanation:

See the angle to the right of 125? Put those angles together, and you get 180 degrees. For starters, we want to find the measure of the angle to the right of 125.

180-125=55

We can basically do this all over again to find w. The angle 55 + w + the square angle is 180 degrees. You can tell by the flat line. So we will find w like this:

180-90-55=w

Thus, w equals 35

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
