Write a quadratic function in standard form having zeros of 2 and -11

Sum of the zeroes = 2+(-11)
                               =-9
product of zeroes =2× (-11)
                               =-22
quadratic equation= x²- x(sum of zeroes) + (product of zeroes)
                                 =x²-(-9)x+(-22)
                  equation⇒x²+9x-22

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

The last one bc that's a calendar
