Answer:
10
Step-by-step explanation:
N(-2,1), P(3,1), Q(3, -1), R(-2, -1)
The polygon is the rectangle with sides 2 and 5
So the area is 2*5 = 10
see attached
the roots of the equation is option D.
Since this is a right angled triangle:
tan(∅) = opposite side/adjacent side
In this triangle:
tan(25°) = x/19
x = 8. 86 ≅ 8.9
