Answer:
87.92
In this case we're trying to find circumference
Formula: c = pi×d
The problem says to use 3.14 for pi
c = 3.14 × 28 = 87.92
<u>Given</u>:
Given that Corey is flying a kite with 105 meters of string.
The string makes an angle of 42° with the ground level.
We need to determine the height of the kite.
<u>Height of the kite:
</u>
The height of the kite can be determined using the trigonometric ratio.
Thus, we have;

From the given data, the values are
, opp = h (height of the kite) and hyp = 105 meters.
Substituting the values, we get;

Multiplying both sides of the equation by 105, we get;



Rounding off to the nearest meter, we get;

Thus, the height of the kite is 70 meters.
B. 4 right angles
perpendicular lines always create 90° angles
Hey I’m sorry but I do not know the answer.
