The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .
The Absolute Value of a number means writing the number without the negative sign .
For Example : the absolute value of -2 is |-2| = 2
In the question ,
an expression in words is given as "12 divided by 2 x the absolute value of 1.3 minus 2.16 "
the above expression in numbers can be represented by
= (12/2)×| 1.3 - 2.16 |
= 6 × | 1.3 - 2.16 |
= 6 × |-0.86|
= 6 × 0.86 .... because |-0.86| = 0.86
= 5.16
Therefore , The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .
The given question is incomplete , the complete question is
Find the value of the expression " 12 divided by 2 x the absolute value of 1.3 minus 2.16 " ?

Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for B
B = 180° - (90 + 40)° = 180° - 130° = 150°
--------------------------------------------------------------
sin40° = 
= 
Multiply both sides by 21
21 × sin40° = a, thus
a ≈ 13.5 ( to the nearest tenth )
--------------------------------------------------------------
cos40° = 
= 
Multiply both sides by 21
21 × cos40° = b, thus
b ≈ 16.1 ( to the nearest tenth )
