[4] in the accompanying diagram, < 2 = 105° and < 5 = 75°. find the
measure of the remaining angles.

1=75

3=75

4&6=105

Step-by-step explanation:

1+2=180

180-105=75(1)

3=5

=75(3)

3+4+5+6=360 & 4=6 , 3=5

[360-(75+75)]÷2=105(4&6)

step-by-step explanation:

you are throwing one dart

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.
