Answer:
22/21
Step-by-step explanation:
Taking the derivative, we have ...
2x·dx +2y²·dx +4xy·dy +3·dy = 0
dx(2x +2y²) +dy(4xy+3) = 0
At the given point, this is ...
dx(2·2 +2·(-3)²) +dy(4·2·(-3) +3) = 0
22dx -21dy = 0
dy/dx = 22/21
The slope of the tangent at the point of interest is 22/21.

Step-by-step explanation:
Answer:
Solution given:
In right angled triangle
ABC.
with respect to <C=40°
opposite side=AB
adjacent=BC=DE=30ft
now
relationship between opposite side and adjacent
is given by tan angle
tan 40°=oppo/adjacent
tan40°=AB/30
AB=tan40*30
AB=25.2
