In circle o, su is a diameter. what is m? 100° 108° 130° 160°

answer: 130

step-by-step explanation:

answer:

the measure of the arc st is 130°

step-by-step explanation:

step 1

find the value of x

we know that

∠sor+∠rot+∠tou=180°

substitute the values

(9x+5)°+(13x+15)°+(9x+5)°=180°

solve for x

(31x+25)°=180°

31x=180°-25°

x=155°/31=5°

step 2

find the measure of the arc st

we know that

arc st=∠sor+∠rot > by central angle

substitute the values

arc st=(9x+5)°+(13x+15)°

arc st=(22x+20)°

substitute the value of x

arc st=(22(5)+20)=130°

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.
