Aquadrilateral has two angles that measure 20° and 275°. the other two angles are in a ratio of 3: 10. what are the measures of those two angles?

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Find the difference (8ab+a+2) - (3ab+6)

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
