If two lines are coplanar, which of the following must be true a: the lines intersect b: the lines never intersect c: the lines are coplanar d: the lines share at least one point

Option 'c' is correct.

Step-by-step explanation:

Since we have given that

If two lines are coplanar, then lines should be parallel or they should intersect each other.

It means, perpendicular lines always intersect to each other but parallel lines never.

So, If the lines are perpendicular then it must intersect, other wise the lines never intersect.

so, the lines are coplanar.

Hence, Option 'c' is correct.

where are the choices?

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 : )
