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.
The formula for the area of a circle (in this case, the disc) is
So, we apply the given radius to the formula to give us our answer:
So, your approximate answer is C.
x- intercept = 5/2
y - intercept = 5
Step-by-step explanation:
the intercepts of a line are found by plugging in x=0 and y = 0
For x-intercept, we put y = 0
and
For- y-intercept we put =0
Given equation is:
Dividing both sides by -4
Putting x = 0
Dividing both sides by 2
So,
x- intercept = 5/2
y - intercept = 5
