Adam is 159 centimeters tall and casts a shadow 105 centimeters in height. If Cara is 140 centimeters tall, how many centimeters

vodomira [7]

Answer:

The answer to your question is 12.55 cm

Step-by-step explanation:

Data

Adam Cara

height = 159 cm height = 140 cm

shadow = 105 cm shadow = x

Process

1.- To solve this problem use the Thales' theorem

Cara's shadow / Cara's height = Adam's shadow / Adam's height

- Substitution

x / 140 = 105 / 159

-Solve for x

x = 105 (140) / 159

-Simplification

x = 14700 / 159

x = 92.45 cm

Cara's shadow is 92.45 cm long.

2.- If both shadows are in line, then Cara must walk forward

105 - 92.45 cm

12.55 cm
