Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
You know two angles, one 90 degrees, and the other 38 degrees. Add 90 and 38 together to get 128
Now 180-128 gets 52 degrees
Angle m is 52 degrees

Answer:
The correct graph is D.
Step-by-step explanation:
Given a quadratic equation :
You can find the roots (where the graph intersects the x-axis) applying the following equation :
and
We define the discriminant as
If then the graph will intersect the x-axis in two points
If then the graph will intersect the x-axis in one point.
Finally, If then the graph won't intersect the x-axis because it will not have real roots.
In this exercise, the graph that doesn't intersect the x-axis is graph D.
Answer:
D
Step-by-step explanation:
A negative discriminant indicates that the quadratic equation has no real roots.
Thus the graph does not touch or intersect the x- axis
The only graph that does not touch or intersect the x- axis is the fourth one
