Step-by-step explanation:
Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54
Circumference of a circle = pi x diameter
pi = 3.14
diameter = radius x 2
diameter = 10 x 2
diameter = 20
Circumference = 3.14 x 20
Circumference = 62.8 ft
