Step-by-step explanation:
An indepentent variable in an investigation, is the variable that will be changed in order to know how its variation affects the dependent variable.
In this case, the dependent variable is the test scores since Dr Washington will study there is the numeber of hours of study affects the grade the students obtain.
Therefore, the hours of study are the independent variable.
It is also a quantitative variable since it can be counted.
Answer:
Step-by-step explanation:
a) The sum of the angles in a triangle is 180 degrees. This means that
Angle A + angle B + angle C = 180
Therefore,
3x + 28 + 5x + 52 + 2x - 10 = 180
Collecting like terms, it becomes
3x + 2x + 5x + 28 + 52 - 10 = 180
10x + 70 = 180
Subtracting 70 from both sides of the equation, It becomes
10x + 70 - 70 = 180 - 70
10x = 110
Dividing both sides of the equation by 10, It becomes
10x/10 = 110/10
x = 11
b) angle C = 2x - 10 = 2 × 11 - 10
Angle C = 22 - 10 = 12 degrees
