A, dilation because the shape got larger. The other three options just move it around
Answer:
α ≈ 76°
Step-by-step explanation:
The vertices of a rectangle are right , that is 90°
Using the tangent ratio in right triangle ABC
tanα = 
= 
= 
= 4, then
α = 
(4) ≈ 76° ( to the nearest degree )
Maybe because the diameter of the circle should equal each side length of te equilateral triangle
answer is: 8 as in a whole number 4/8
So a straight line equals 180 degrees so you need to subtract the 69 degrees from 180 to get 111 degrees
You then need to subtract the 1 from 111 to get 110
Now the missing angle is
5x=110
You then divide 110 by 5 to get 22
X=22
