Given :
Two vertical buildings 57 meters apart are 158 meters and 237 meters high.
To Find :
The angle of elevation from the top of the shorter building to the top of the taller building.
Solution :
Distance between height of building, h = 237 - 158 = 79 m.
Distance between these building , d = 57 m.
Now,

Therefore, the angle of elevation from the top of the shorter building to the top of the taller building is 54.19°.
Hence, this is the required solution.
Answer:
$12.55
Step-by-step explanation:
20-7.45=12.55
X is minus 30 over 7
So you can cross multiply and multiply the values.
Then you can solve it like a normal equation
