The mean increases when the outlier is removed
Answer:
Step-by-step explanation:
X=70, y=55
The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.
Then use the triangle angle sum theorem and set the equation to 180.
55+55+x=180
110+x=180
x=70
The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
Answer:
x = 64 degree , 2x = 128 degree
Step-by-step explanation:
2x = 128 (being alternate interior angles)
x = 128/2
x = 64 degree
2x
=2*64
=128 degree
