Need your quick marc is writing statements to prove that the sum of the measures of interior angles of triangle pqr is equal to 180°. line m is parallel to line n. line n is parallel to line m. triangle pqr has vertex p on line n and vertices q and r on line m. angle qpr is 85 degrees. segment pq makes 45 degree angle with line n and segment pr makes 50 degree angle with line n. which is a true statement he could write? angle prq measures 45°. angle pqr measures 85°. angle pqr measures 40°. angle prq measures 50°. photo

i checked ad yes, it is the right answer!

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.

can you complete your sentence? i could !
