discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
Answer:
Angle A =35
Step-by-step explanation:
ok that is a triangle
look exterior plus interior is 180
corresponding angles
x+74
now lets solve for the angle a
triangle = 180 degrees
180=73+x+74+37+x
combine like terms
x=−2
now plug in for angle a
37+(-2)
=35
