Question

find the absolute value of -x=12​

Answer 1

Answer:

12

Step-by-step explanation:

we can write   -x   as    -1(x).

-1(x) = 12

x = ( 12/-1 )

x = -12

We know that absolute value of any number is its positive value or postive number.

Hence,

x = |-12 |

x = 12

absolute value of -x = 12 is 12

Let the height of tower be h

and the distance between the foot of tower to the point of sigh be x

[ previous solution is in the attachment ]

√3 ( 3h - h ) = 7√3

2h = 7√3/√3

2h = 7

h = 7/2

h = 3.5 m

Height of tower is 3.5m
