Explanation:
Please follow the diagram in attachment.
As we know median from vertex C to hypotenuse is CM
We are given length of CG=4
Median divide by centroid 2:1
CG:GM=2:1
Where, CG=4
ft
Length of CM=4+2= 6 ft
In
Using trigonometry ratio identities
ft

<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
