(TCO B) The symbol shown as a three-sided box that is connected to the step it references by a dashed line is what?

Annotation symbol

Explanation:

A flowchart is a diagram that is used to show and represent a workflow, process or algorithm. Flow charts are used in designing processes or programs. Flow charts are usually designed using boxes and arrows.

An annotation symbol is a symbol used in flowchart to hold comments and it is usually represented by a three-sided box connected to the step it references by a dashed line.

for this, you need the pythagorean theorem, which is a^{2}+ b^{2}= c^{2}

your a should be 12, and your b should be 35. so now you can solve for c, which equals 37 miles.

so the answer is 37 miles

a few, because i should have plenty.
