Identify the value of c in the following quadratic function \displaystyle f\left(x\right)=-2x^{2}+3x-4f(x)=−2 x 2
+3x−4

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

d. you cannot tell because there are no values shown.
