A circle has radius 25cm long. A chord of length 14cm is drawn from the center of the circle of the circle. Calculate distance between the chord and the center of the circle

Step-by-step explanation:

r=25 cm

chord=14 cm

1/2 chord=1/2×14=7 cm

using Pythagoras theorem

d=√(25²-7²)=√(625-49)=√(576)=24 cm

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

answer: y = -2.5x - 15

              (-6,0)
