The lengths of parallel chords which are on opposite sides of the Centre of a circle are 24 cm and 10 cm. If radius of the circle is 13 cm, then the distance
between these chords is
A) 12 cm B) 10 cm C) 17 cm D) 8 cm

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet

It is 5.8 you add all of the up to equat 180 then solve the equation

1) add 6 to 24, write the rest of the equation 10-2x= 30 subtract 10 from 30 2x=20 divide 20 by 2 and x=102) add 3 to -9 write the rest of the equation 4x+3=-6 subtract 3 from -6 4x=-9 x= -2.25  i don't know the rest sorry
