Circles

In the circle with a radius 7.5 cm are constructed two parallel chord whose lengths are 9 cm and 12 cm. Calculate the distance of these chords (if there are two possible solutions write both).

Correct answer:

x =  10.5 cm
y =  1.5 cm

Step-by-step explanation:

r2=7.52=x12+(9/2)2 r2=7.52=x22+(12/2)2 x1=6 cm x2=4.5 cm  x=x1+x2=10.5 cm
y=x1x2=1.5 cm
