In quadrilateral dbca, name the angles which are consecutive with angle d.

Angle A and angle B.

Step-by-step explanation:

A quadrilateral is a polygon with four sides or say four vertices.

If we have a quadrilateral DBCA, we can say that the angles which are consecutive with angle D are angle A and angle B.

The reason being, in simple words, that angle B or vertex B is adjacent to angle D.

Moreover, when a quadrilateral DBCA is formed, the side D is again going to be adjacent to side A so angle A will also be consecutive to angle D.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
