Supplementary means they add to 180

180 = (5x+20) + 50

180 = 5x + 70

5x = 110

x = 22

Supplementary angles are pair of angles that to make a straight angle, or 180°. Here, we're told that the angles (5x + 20)° and 50° are supplementary, which means that

(5x + 20) + 50 = 180

Solving for x, we find

5x + 70 = 180
5x = 110
x = 22

If the discriminant is 16 in a quadratic equation what is true about its solutions
olganol [36]
If the discriminant is a positive number, there will be 2 possible solutions. If you replace the entire section of b²-4ac with 16, you will see that the equation becomes; (-b+-√16)/2a --> leading to an answer with the + and another with the -. 

If the discriminant is 0, there will be 1 possible solution, (again replace this into the discriminant value) (-b)/2a ---> this formula is used to also find the x coordinates of a vertex, fyi. 

If the discriminant is a negative number, there will be no solution (since squareroot of a negative number is not possible) 

Hope I helped :)
