Pythagoras theorem: leg 1 squared + leg 2 squared = hypotenuse squared
In the diagram, the triangle has angles 90 and 45. So the other angle in the triangle must be 45 degrees as well.  (180 - 90 -45 = 45)
This means it is an isosceles triangle (since two angles are the same), so the two legs have the same length.
So we can say that length of leg1 = x, and the length of leg2 also equals x
Now let's use pythagoras' theorem:
leg1 = x
leg2 = x
hypotenuse = 16
x^2 + x^2 = 16^2
       2x^2 = 16^2
       2x^2  = 256
         x^2 = 128
         x = √(128)
         x = 8√2 
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
A major arc is an arc that is greater than 180 degrees.
A minor arc is an arc less than 180 degrees.
An acute angle is an angle less than 90 degrees.
A central angle is the angle created in the center of a circle with 2 sides being the radius.
<em>Thus, we can see in the figure that we are talking about the angle so we can eliminate major arc and minor arc.</em>
<em>Now, we clearly see that the angle is greater than 90 degree so it cannot be acute angle.</em>
<em />
The correct answer is central angle as it goes with the definition.
 
        
             
        
        
        
Answer:
-2 + 9
 + 9
Step-by-step explanation:
    0 + (-7x) + 1
 + (-7x) + 1
+ <u>-2</u> <u>  + 7x + 8</u>
<u>  + 7x + 8</u>
   -2 + 0x + 9
 + 0x + 9
or
-2 + 9
 + 9
