Answer:
x = 116° , y = 20°
Step-by-step explanation:
Since, measure of angle subtended on the center of the circle is twice the measure of angle subtended on the circumference of the circle.
Now, by angle sum property of a quadrilateral.

Answer:
8 cookies: 1 cookie =$1.25
12 cookies: 1 cookie =$1.33
Step-by-step explanation:
The formula for price per unit is : 
Lets first work out the price per unit for the 8 cookies. You can do this by dividing the price of 10 by the amount of 8, this gives you $1.25. This means that the price per cookie is $1.25.
Now to work out the price per cookie for 12 cookies. You can do this by dividing the price of 16 by the amount of 12, this gives you $1.33. This means that the price per cookie for this offer is $1.33.
1) Divide 10 by 8.

2) Divide 16 by 12.

Answer:
(C)26 units
Step-by-step explanation:
Since point B bisects AC into two equal parts
AB=BC
Since the two right triangles have side BD in common, we can then say that the two triangles are congruent and the length of the hypotenuses (AD and DC) are equal.
If AD=DC
8x-1=6x+9
8x-6x=9+1
2x=10
x=5
Now,
AB=3x-2
=3(5)-2
=13 Units
Since AB=BC
AC=AB+BC
=13+13
AC=26 units
The measure of AC is 26 units.

Answer:
The answer is 13 7/8
Step-by-step explanation:
