Step-by-step explanation:
<5, 2> - <2, -3> = <5 - 2, 2 - (-3)> = <3, 5>
LCM of 10 & 4 = 20
8/10 * 2 & 5/4*5
16/20 & 25/20
THE 2 RATIONAL NUMBERS BETWEEN 16/20 & 25/20 ARE
17/20,18/20 ect
Please find the attached diagram for a better understanding of the question.
As we can see from the diagram,
RQ = 21 feet = height of the hill
PQ = 57 feet = Distance between you and the base of the hill
SR= h=height of the statue
=Angle subtended by the statue to where you are standing.
=
which is unknown.
Let us begin solving now. The first step is to find the angle
which can be found by using the following trigonometric ratio in
:

Which gives x to be:

Now, we know that
and
will get added to give us the complete angle
in the right triangle
.
We can again use the tan trigonometric ratio in
to solve for the height of the statue, h.
This can be done as:





Thus, the height of the statue is approximately, 8.45 feet.
Answer:
Given,a= -2 and d=8
an=a+(n-1)d
= -2+(n-1)8
= -2+8n-8
=8n-10
