the supplement of an angle is 3.5 times as large as the angle. find the angle.

140° and 40°

Step-by-step explanation:

So its telling you there are two angles of a supplementary angle and one of them is 3.5 times larger than the other one.

So lets say 3.5x and x.

Since a supplementary angle has the sum of 180 degrees,

add 3.5x and x.

3.5x+x=180

4.5x=180

x=40

3.5x=140

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 : )
