Answer:
19.8m
Step-by-step explanation:
In the attached diagram:
- The man's eye level is at point A,
- The height of the tree is BC.
- The angle of elevation at A is 61 degrees.
- The distance of the man at A to the tree BC is 11 meters.
This forms the right triangle ABC.
We want to determine the height labeled h.
Using Trigonometry:
The height of the tree is 19.8 meters to the nearest tenth of a meter.

Answer:
RT = 20
Step-by-step explanation:
Point S is on line segment
R------------S------------T
RS + ST = RT
Given
ST=3x-8
RT=4x
RS=4x-7,
Step 1
We find x
4x - 7 + 3x - 8 = 4x
4x + 3x -7 - 8 = 4x
7x - 15 = 4x
7x - 4x = 15
3x = 15
x = 15/3
x = 5
Step 2
We find RT
RT = 4x
x = 5
RT = 4 × 5
RT = 20
The numerical length of RT is 20
