Question

. A building 88 ft high casts a 176-ft shadow. Sarah casts a 8-ft shadow. The triangle formed by the building and its shadow is similar to the triangle formed by Sarah and her shadow. How tall is Sarah?

Answer 1

Sarah has an angle to her shadow and the building has an angle too. Let's suppose the shots were taken in the saame time ( of the day) and that x is the hight of the wee-woman

88:176=x:8

x=88×8:176

x=4 units
