What is m ZPQR?

Somebody help me find the degrees of m\PQR

PQR=133°

Step-by-step explanation:

PQR+RQS = 180

(3x -5)+(x+1)=180

4x -4=180

4x =180+4

4x =184

x=184/4

x=46

PQR= 3x-5=3(46)-5=138-5=133

I hope I helped you^_^

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.
