Answer:
x < -12
Step-by-step explanation:
Given the inequality
-2(x + 3) < 6 - x
Expand
-2x - 6 < 6 - x
Collect the like terms;
-2x + x < 6 + 6
-x < 12
Multiply through by -1
-1(-x) < -1(12)
x < -12

Step-by-step explanation:
<em>Height of the pole (DC) is 57.2709m</em>
Step-by-step explanation:
Here, Wire DA and Wire DB supports a pole.
Given that Angle, A=54 , B= 72.
Also, AB = 23m
Now, Taking triangle BCD and Using basic trigonometry
Height of pole H = DC


Now, Taking triangle ACD and Using basic trigonometry


From figure, we know that
AC = AB + BC
AC - BC = AB = 23
Replacing values of AC and BC

Now, TanB= Tan72 =3.0776 and TanA = Tan54=1.3763




Thus, Height of thepole is 57.2709m
