Abuilding 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?

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

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
