Answer:

Step-by-step explanation:
We want to write the trignometric expression: 

As an algebraic equation. 
First, we can focus on the inner expression. Let θ equal the expression: 

Take the secant of both sides: 

Since secant is the ratio of the hypotenuse side to the adjacent side, this means that the opposite side is: 

By substitutition: 

Using an double-angle identity: 

We know that the opposite side is √(u² -100), the adjacent side is 10, and the hypotenuse is u. Therefore: 

Simplify. Therefore: 

 
        
             
        
        
        
Answer:
From the graph attached, we know that  by the corresponding angle theorem, this theorem is about all angles that derive form the intersection of one transversal line with a pair of parallels. Specifically, corresponding angles are those which are placed at the same side of the transversal, one interior to parallels, one exterior to parallels, like

 and  .
.
We also know that, by definition of linear pair postulate,  and
 and  are linear pair. Linear pair postulate is a math concept that defines two angles that are adjacent and for a straight angle, which is equal to 180°.
 are linear pair. Linear pair postulate is a math concept that defines two angles that are adjacent and for a straight angle, which is equal to 180°.
They are supplementary by the definition of supplementary angles. This definition states that angles which sum 180° are supplementary, and we found that  and
 and  together are 180°, because they are on a straight angle. That is,
 together are 180°, because they are on a straight angle. That is, 
If we substitute  for
 for  , we have
, we have  , which means that
, which means that  and
 and  are also supplementary by definition.
 are also supplementary by definition.
 
        
                    
             
        
        
        
An art gallery is a 6-story square pyramid with base area of half an acre. Estimate the volume in cubic yards of the art gallery. In your calculations, use 1 acre = 4840 yd2 and 1 story = 10 ft.

Step-by-step explanation:
if b+c=0
b=-c
x^b=x^-c
so
1/[2(x^b)+1]
