Ineed to know how to find the measurements of angles 1,2,and3 step by step

so to find angle one you just subtract the other angles from 180°

180°-33°-92°=55°

angle 2 is going to be equal to the adjacent angle every time so it's equal to 92°

angle 3 you just subtract everything from 360°

360°-90°-115°-92°= 63°

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.
