Question

this triangle is a scaled copy. it was scaled by a scale factor of 5. suppose you want to scale it back to its original size. what is the base and height of the original triangle? original triangle scaled copy base cm 30 cm height cm 75 cm

Explanation:

Step1: Recall scale - factor formula

To find the original length from a scaled - length, we use the formula: Original length = Scaled length $\div$ Scale factor.

Step2: Calculate the original base

The scaled - copy base is 30 cm and the scale factor is 5. So, the original base $b=\frac{30}{5}=6$ cm.

Step3: Calculate the original height

The scaled - copy height is 75 cm and the scale factor is 5. So, the original height $h = \frac{75}{5}=15$ cm.

Answer:

Base: 6 cm
Height: 15 cm
