In which quadrant is (1/2, -1.8)?
2 answers:
Answer:
The point lies in 4 th quadrant.
Step-by-step explanation:
Given : Point
To find : In which quadrant is point exist ?
Solution :
We know that,
In quadrant 1 - x and y points are positive
In quadrant 2 - x is negative and y is positive.
In quadrant 3 - x and y both are negative.
In quadrant 4 - x is positive and y is negative.
We have given point
Where, x is positive and y is negative.
Therefore, The point lies in 4 th quadrant.

We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
see the attached figure to better understand the problem
angle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft
the answer is
2.12 ft
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
see the attached figure to better understand the problem
angle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft
the answer is
2.12 ft
