Answer:
x = 53 degree
Step-by-step explanation:
53 degree angle = x angle( alternate exterior angle)
Therfore, x = 53 degree

Answer:
130 degrees
Step-by-step explanation:
let the angle be x
2x+45+55=360(Sum of angles in quad)
2x=260
x=130
Make the same part of the first one
8r + 206 + 7r +79 = 360
15r + 285 = 360
15r = 75
r = 5
7(5) + 79
35 + 79
angle YMB is 114°
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is 
The number of observation is 
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as



So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
