** **The diagram at right represents an acrobat’s sequence on a tightrope, where

*m*represents the distance in feet that she covers each time she does a leap.

How long is each of her leaps? How can you tell?

The diagram reveals that

is the same distance as.

Use these distances to create an equation that will allow you to solve for.Write and solve an equation to find the length of each leap.

See part (a).

Simplify the equation.

Solve for

. feetHow long is the tightrope?

Substitute

in the equation with the answer you found in part (b).feet
