Geometry

Please help

Step-by-step explanation:

The information provided says that angle 1 is supplemental to angle 2 which means that both angles added together equal 180 degrees. Since angle 1 equals 68 degrees it means that 180 degrees minus 68 degrees of angle one gives us the answer of angle 2 equals 112 degrees. Angle 1 is complimentary with angle 3 which means they equal 90 degrees together and with angle 1 being equal to 68 degrees then angle 3 equals 22 degrees. Lastly angle 2 minus angle 3 = 112 - 22 = 90 degrees

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 : )
