Answer: First option.
Step-by-step explanation:
 You can idenfity in the figure that  is formed by two secants that intersect outside of the given circle.
 is formed by two secants that intersect outside of the given circle. 
 It is important to remember that, by definition:
  
 Knowing this, you can set up the following equation:
 
 Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle  .
. 
 This is:
 
 
        
             
        
        
        
Answer:
a square is a rectangle as it's a shape with 4 sides with 90degree angles, and pairs of sides are equal.
 
        
                    
             
        
        
        
Answer:
1. A. 1
2. D. 
Step-by-step explanation:
Properties used:
- Power of a Power Property
- Product Property
- Quotient Property
- Zero Exponent Property
1. First, let's deal with the numerator.
 can be turned into
 can be turned into  by using the Power of a Power Property.
 by using the Power of a Power Property.
And then use the Product Property, 
So now, our fraction is this: 
All number over itself in a fraction is equal to 1. But you can also do this the mathmatic way using the Quotient Property:  or
 or  . Which then you plug the numbers in:
. Which then you plug the numbers in:  . And since we know that in Zero Exponent Property:
. And since we know that in Zero Exponent Property:  , we can see that
, we can see that  . So either way, we get 1.
. So either way, we get 1.
So the answer is 1, which is A
2. Power of a Power Property: 
So plug the numbers in the property:  =
= 
Product Property: 
We plug the equation in with  turned into
 turned into  ---
 ---

So the answer is  , which is D
, which is D

Answer:
1/4 & 1
Solution:
1/2 * 1/2 = (1*1)/(2*2)
1/2 + 1/2 = (1+1)/(2) = 2/2 = 1
