Need some help! <br>help giving 10 points ​
steposvetlana [31]

Answer:

The remaining lenghts are x = 20.364\,cm and y = 12.925\,cm.

Step-by-step explanation:

Given that there are two triangles opposite to each other and between two parallel lines, then both are similar, meaning than following relationships exist:

\frac{AC}{CD} = \frac{BC}{CE} = \frac{AB}{DE} (1)

If we know that AC = 11\,cm, CD = 28\,cm, BC = 8\,cm and DE = 32.9\,cm, then the missing lengths are, respectively:

\frac{11\,cm}{28\,cm} = \frac{8\,cm}{x}

x = \frac{(28\,cm)\cdot (8\,cm)}{11\,cm}

x = 20.364\,cm

\frac{11\,cm}{28\,cm} = \frac{y}{32.9\,cm}

y = \frac{(11\,cm)\cdot (32.9\,cm)}{28\,cm}

y = 12.925\,cm

The remaining lenghts are x = 20.364\,cm and y = 12.925\,cm.
