If you are 6 ft tall and stand 15 ft away from the bottom of a building that is 170 ft tall and look up to the roof, what is the angle of elevation from your head to the top of the building?

The angle of elevation from your head to the top of the building is 84.95°

Step-by-step explanation:

Given : you are 6 ft tall and stand 15 ft away from the bottom of a building that is 170 ft tall .

We have to find the angle of elevation from your head to the top of the building.

Consider the figure below,

Where AB represent 170 ft tall building, C represents your head.

BC   is the distance from the bottom of a building to you.

We have to find α the angle of elevation.

Using trigonometric ratio,

here,

Substitute , we get,

Thus, the angle of elevation from your head to the top of the building is 84.95°

$12. that is my answer.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
