Question

AD=20, BC=2, AB= x 12,
and CD=x+ 12. Find x.

Answer 1

• Here, the whole line segment is AD.
• So, AB + BC + CD = AD.
• Given, AD = 20
• BC = 2
• AB = 12x
• CD = x + 12
• Therefore,

AB + BC + CD = AD

or, 12x + 2 + x + 12 = 20

or, 13x + 14 = 20

or, 13x = 20-14

or, 13x = 6

or, x = 6/13

• So, x = 6/13

Answer:

x = 6/13
