Look at the triangle:
13 cm
5 cm
12 cm
What is the value of sin xº? (1 point)
12 - 13
13 - 5
13 = 12
5 + 13

Which answer is it for it to be simplified completely?

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

Find the area of the triangle shown 3 by 6
