18. In a coordinate plane, triangle ABC has vertices of A(1, 1), B(1,5), and C(6, 1).
:
a. Triangle ABC is reflected across the x-axis, resulting in triangle A'B'C'.
What are the coordinates of Point B'?
b. Triangle A'B'C' is then dilated by a scale factor of 2 with the origin as the center of
dilation, resulting in triangle A"B"C". What is the length of line segment A"B"?

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
