Answer:
![60^\circ](https://tex.z-dn.net/?f=60%5E%5Ccirc)
Step-by-step explanation:
Angle ABC is formed by two tangents drawn from point B outside the circle.
The measure of angle ABC is half the difference between the two intercepted arcs. One of those arcs is arc ADC, the big one with measure 240 degrees. The smaller arc, closer to point B, is arc AC with measure 120 degrees.
![m\angle ABC=\frac{1}{2}(240^\circ - 120^\circ)=60^\circ](https://tex.z-dn.net/?f=m%5Cangle%20ABC%3D%5Cfrac%7B1%7D%7B2%7D%28240%5E%5Ccirc%20-%20120%5E%5Ccirc%29%3D60%5E%5Ccirc)

Answer:
one pound of apple cost $2.5
Step-by-step explanation:
Let the amount they both spent at the grocery store be y and x be the price of apples per pound.
Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).
Equating both expressions, 5x = 3x + 5
collecting like terms,
5x - 3x = 5
2x = 5
dividing both sides by 2, we have
x = 5/2
x = 2.5
So one pound of apple cost $2.5
Answer:
(5-2z)(5+2z)
Step-by-step explanation:
25 -4z^2
Rewriting
5^2 - (2z)^2
This is the difference of squares a^2 - b^2 = (a-b)(a+b)
(5-2z)(5+2z)
