Point d is between points r and s on rs(line on top). find the length of-
rs(line on top) if rd = 7 and ds = 12.

a: 1
b: 5
c: 18
d: 19

select the best answer from the choices provided

a?
b?
c?
d?

The best answer from the choices provided is

Option D : 19

Step-by-step explanation:

Given:

RS is a Straight Line,

Point D is between points R and S on RS(line on top)

Such that

RD = 7

DS  = 12

To Find:

Length of RS = ?

Solution:

RS is a Straight Line  ................Given

Point D is between points R and S on RS(line on top)

Such that

R - D - S

Therefore By Line Addition Property we will have

Substituting the given values we get

The best answer from the choices provided is

Option D : 19
