A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle. What equation represents the length of the third side if the second side is length s?

s - 10

2s + 10

s + 10

2s - 10

a

Step-by-step explanation:

let the third side and second side be x and s respectively

a/c to question,

X = s - 10

the first one, all those points on the line just make a strait line.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
