What is the measure of angle q°?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

What is the missing reason in the proof? segment addition congruent segments theorem transitive property of equality subtraction property of equality?

If abcde is reflected over the x-axis and then translated 3 units left, what are the new coordinates d?
