How many grey slices are there
Answer:
55°
Step-by-step explanation:
One triangle = 180° Therefore 90°+35°+ Unknown acute angle = 180°
125°+ Unknown acute angle = 180°
Unknown acute angle = 180°-125°
Unknown acute angle =55°
We know that the lace is also what we would call the circumference of the circle.
And we also know that the circumference of a circle is represented by the equation:

We then can use the length of the lace (12.56 ft) to solve for the diameter (d) of the rug. Let us solve for that now:


We now know that the diameter of the rug is
4 ft.
