The angle of depression from the top of the building is missing, therefore, we will consider it to be 60°, for your understanding.
Now,
According to the right triangle rule, we are given the angle, the adjacent side, and we have to find the opposite side.
Therefore,
Using SOH CAH TOA laws,
<span><span>SOH means,
Sine Ф = Opposite / Hypotenuse
</span><span>
CAH means,
Cosine Ф = Adjacent / Hypotenuse
</span><span>
TOA means,
Tangent Ф = Opposite / Adjacent
Where,
Ф is the angle of depression.
Hence,
Using Tangent Ф = Opposite / Adjacent</span></span>
Tangent 60° = Opposite / 60
1.73 = Opposite / 60
1.73 × 60 = Opposite
Opposite = 103.8 feet away from the <span>base of the building</span>
Answer:
208cats
Step-by-step explanation:
⅝=tongue
³/16=straw=39cats
⅝+³/16=13/16
meaning total number of cats is 16/16
If ³/16=39cats
16/16=?
39×16/3
=208cats

The teacher would need 40 centimeters of tape to hang 10 student projects.
Step-by-step explanation:
Given,
Tape used to hang projects = 36 centimeters
Number of projects hanged = 9
We will find unit rate;
9 projects = 36 centimeters
1 project = \frac{36}{9}\ centimeters
9
36
centimeters
1 project = 4 centimeters
Therefore,
Tape needed to hang 10 projects = 4*10 = 40 centimeters
The teacher would need 40 centimeters of tape to hang 10 student projects.
