D is the correct answer to this question
Y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)
x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)
Therefore, m/_x = 48 degrees.
Both of these variables represent a common measure used in chemistry.
The amount of material/volume is the material’s concentration.
The rate is the reaction is increase by altering the concentration.
