5 don't have lowest term only the 6 and it's 2 but if a number like 5 doesn't change so 6 doesn't change if not then divide 5 to 6.
You can do
83 - 5 to find the answer
So that's
78 or
5 + 78 = 83
Answer:
30.11 meters ( approx )
Step-by-step explanation:
Let x be the distance of a point P ( lies on the building ) from the top of the building such that AP is perpendicular to the building and y be the distance of the building from point A, ( shown in the below diagram )
Given,
Point A is 8.20 m above level ground,
So, the height of the building = ( x + 8.20 ) meters,
Now, 1 degree = 60 minutes,
⇒ 


By the below diagram,




Now, again by the below diagram,



Hence, the height of the building = x + 8.20 = 30.11 meters (approx)
I think you are correct actually.
The first option and the third one
