Answer:
Step-by-step explanation:
The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.
Tan θ = 
= 
the the distance, d = x ÷ Tan θ
Assume the angle of elevation of the top of the tree is
, and the height of the tree is 10 m, then the distance, d, across the river would be;
d = 
= 17.3190
d = 17.32 m
The sketch to the explanation is attached to this answer for more clarification.
Answer:
4n+2
Step-by-step explanation:
The common difference between the terms is 4 which means that the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:

where a_n is the nth term, a_0 is the first term and d is the common difference between them.
We know that

Putting the value in general formula:

So the generalized pattern is 4n+2 ..
Answer:
<h3>option :c is correct..ok</h3>
Is this what you need or? Y= 1/4x +3
In order to compare the fractions, we need to convert them into decimal form,
1/8 = 0.125
3/20 = 0.15
As 0.15 > 0.125
In short, Your Answer would be 3/20 > 1/8
Hope this helps!
