Answer:

Step-by-step explanation:
To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.
 is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.
 is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.
We can use Pythagorean's Theorem to find the hypotenuse (let  represent the length of the hypotenuse):
 represent the length of the hypotenuse):




Thus, we know the adjacent is 10, and the hypotenuse is  . This means
. This means  .
.
Hope this helps!
 
        
             
        
        
        
<u>Answer:</u>
"It is used when you solve an equation in algebra" is the untrue statement. 
<u>Step-by-step explanation:</u>
"It is used when you solve an equation in algebra."
When you solve an algebra problem, you are not using deductive reasoning. You are using the information in front of you to correctly answer. 
"It is used to make broad generalizations using specific observations." 
This is exactly what deductive reasoning is, you are making generalizations and coming up with your own conclusions through observation. 
"It is used to prove basic theorems." 
This is also true, you can use deductive reasoning by using your specific observations and drawing conclusions to prove the theorems. 
"It is used to prove that statements are true."
Using your own observations, you can draw your own conclusions to prove what you are saying is factual. 
 
        
             
        
        
        
Answer: 1  teashirt=7 L
                1 hat= 3L
Step-by-step explanation:
2 T shirts= 31 -  17
2 T shirts= 14 
1 T shirt=14/2
1 T = 7 L
14L+ 1H=17 L
one hat = 17 - 14=3 L
