Question

Helllpppp pleaseeeeeee

Answer 1

For this, we will be using the triangle inequality theorem, which is $B+C>A\\ A+C>B\\ A+B>C$

In this case, let A = 7, B = 1, and C = 7.

$1+7>7\\ 8>7 (true)$

$7+7>1\\ 14>1 (true)$

$7+1>7\\ 8>7 (true)$

Because all the inequalities are true, this is a possible triangle.
