Explain the possible physical impact on learners who spend more time in online education​

My guess is that students who do online school will do less exercise and get less vitamins from the sun.

Explanation:

Doing online can cause students to stay at home all day sitting down, and can lead to health problems.

a, b, c - sides of a triangle

a + b > c

a + c > b

b + c > a

we have a = 5m and b = 11m. substitute:

5 + 11 > c

16 > c → c < 16

5 + c > 11         subtract 5 from both sides

c > 6

11 + c > 5         subtract 11 from both sides

c > -6

c < 16 and c > 6 and c > -6

thereofre your answer is 6m < c < 16m
