In this attached picture according to the conditions of the problem we have an isosceles trapezoid and since we know that legs are equal (AD=BC=5 cm), we have to calculate bases and height in order to find the area. Working with the triangle BCD, we apply Pythagoras theorem and find that CD = = 10 cm. Since BDC is a right triangle, applying theorem for the area of triangles, we find that
and BF=
. Since ABCD is an isosceles trapezoid, triangles ADE and BFC are congruent with Angle Side Angle theorem. Then, DE=FC and with the help of Pythagoras theorem, DE=FC=2.5 cm. Then, AB=EF=5 cm and the area of the trapezoid is
Answer:
The equation of the tangent line to the curve
3 x - y = 2
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given function = f(x,y) = ...(i)
Differentiating equation (i) with respective to 'x' , we get
apply formula
<u><em>step(ii):-</em></u>
⇒
⇒
Taking common d y/d x
put At (0,2)
slope of the curve m = 3
<u><em>Step(iii)</em></u>:-
The equation of the tangent line to the curve
y - 2 = 3 ( x - 0 )
3 x - y = 2
<u><em>Final answer:-</em></u>
The equation of the tangent line to the curve
3 x - y = 2
