Answer:
Ren was 27.5 meters away from her family.
Step-by-step explanation:
Ren Qian was at a height of 10 meters to the ground. Let the distance from her vertical point on the ground to her family (i.e the ground distance) be represented by x.
But the angle of depression is measured with respect to the horizontal plane, so;
the vertical angle = 
- 20°
= 
Applying the appropriate trigonometric function, we have;
Tan θ = 
Tan = 
⇒ x = 10 x Tan
= 10 x 2.7475
= 27.475
x = 27.5 meters
Ren was 27.5 meters away from her family.
Answer: m=-1.

Step-by-step explanation:
<em>The question is incomplete as what is required of the question is not stated.</em>
<em>However, since the question is only limited to distance, a likely question could be to calculate the distance from Bayville to Colleyville.</em>
Represent the distance from Atlanta to Colleyville with AC
Represent the distance from Atlanta to Bayville with AB
Represent the distance from Bayville to Colleyville with BC
So, we have that:
The relationship between AB, AC and BC is:
Make BC the subject of formula:
Convert fraction to decimal
<em>Hence, the distance from Bayville to Colleyville is 14.8 miles</em>
The answers are:
3:d
4:c
5:b
6:c Note: I am not 100% sure.
