Answer:
39.06 m
Step-by-step explanation:
Given that,
Height of the building, h = 50 m
The angle of elevation at top of building is 52° when seen from a point on level ground.
We need to find the distance between point and foot of the building. Let the distance be d. Using trigonometry to find it. So,
Where
P is perpendicular
B is base.
So,
So, the distance between point and foot of the building is 39.06 m

Answer:
$90.75
Step-by-step explanation:
103*100=(13.5%+100%)*x
10300=113.5x
x=10300/113.5
x=90.74889868
x=$90.75
