Answer:
Step-by-step explanation:
Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region. For example, this graph shows the inequality .
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:
<h2>n = - 8</h2>
Step-by-step explanation:
<u>Expand the terms in the bracket</u>
That's
Subtract 2n from both sides of the equation
Subtract 20 from both sides of the equation
<u>Divide both sides by 2</u>
We have the final answer as
<h3>n = - 8</h3>
