Answer:
9
Step-by-step explanation:
he has 2 shirts for 1  pair(s) pants so if you multiply 9 times 2 you get 18 and if you multiply 9 time 1 you get  your answer which  is 9
 
        
             
        
        
        
Answer:
21-2x
Step-by-step explanation:
11-2(x-5)
11-2x+10
21-2x
not completely sure if im right... if i am can you mark me brainliest
  
        
                    
             
        
        
        
Answer : 110 degree
To find angle 1 , we apply outside angle theorem  Lets name each point  Measurement of arc EF=280 degrees  
Measurement of arc GH = 60
Angle D = angle 1
Please refer to the theorem attached below  

Now we plug in the values

angle 1 = 110
Measurement of angle 1 = 110 degrees
 
        
             
        
        
        
Since you need a little bit of trigonometry to solve this problem, 
I'm pretty sure you've had a little bit of trigonometry in class before 
you were assigned to solve this problem.
-- The shaded triangle comes from taking the equilateral triangle and 
either folding it in half or cutting it in half.
-- The base that the new triangle is standing on is 1/2 the base of the 
equilateral triangle, so it's 7 cm long.
-- The acute angle at the right end of the base is the same as it was in 
the equilateral triangle . . . 60 degrees.
--  The tangent of 60 degrees is (opposite side)/(adjacent side) = x / 7 cm
              tan(60) = x/7
-- Multiply each side of this little equation by 7 :   7 tan(60) = x
 
If you don't have the tangent of 60 degrees in your pocket, you can 
find it with your calculator.  Multiply it by 7, and Shazam, you know 'x' .
