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:
Height is 7m
Step-by-step explanation:
B = 10 feet area = 35 feet 2 Find the height of the triangle.
Area of triangle = 1/2 b×h
35 = 1/2(10×h)
35 × 2 = 10h
70 = 10h
h = 70/10
h = 7m
