The distance from the center of a circle and a chord is 15 cm. If the radius of the circle is 20 cm, what is the length of the chord?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.

let "a number" = "x"

note that increased = +

x + 3.5 = -4.3

solve for x. note the equal sign. what you do to one side, you do to the other. subtract 3.5 from both sides

x + 3.5 (-3.5) = -4.3 (-3.5)

x = -4.3 - 3.5

x = -7.8

-7.8 is your answer for x
