we will check each options
option-A:
The modulus represents the distance between the complex number and the origin
we know that modulus is a kind of distance
For example: if we have to find modulus of x+iy
we get
that is also distance between (0,0) and (x,y)
so, this is TRUE
option-B:
It is also similar to Pythagoras theorem
so, this is also TRUE
option-C:
we got modulus formula
we know that value of sqrt can never be negative because it will always result in positive value
so, this is FALSE
option-D:
It is also similar to absolute value
so, this is TRUE
Answer:
47
Step-by-step explanation:
(2x + 3) + (5x - 8) = 72
2x + 3 + 5x - 8 = 72
(2 + 5)x + (3 - 8) = 72
7x - 5 = 72
7x = 72 + 5 = 77
x = 77/7 = 11
BC = 5x - 8 = 5 (11) - 8 = 55 - 8 = 47
To check solution: AB = 2x + 3 = 25, and AB + BC = AC = 72, so 25 + 47 = 72 verifies answer
