Hey!
You have to use the Pythagorean Theorem
a² + b² = c²
a = 10
10² = 10 × 10 = 100
b = 11
11² = 11 × 11 = 121
100 + 121 = 221
√221 = 14.9(rounded)
Answer ⇒ 14.9
Hope this helps! :)
        
                    
             
        
        
        
It's B - 1/√3
because tan is opposite side over adjacent
        
             
        
        
        
Answer:
A. 
Step-by-step explanation:
Each mark represent 0.1 unit, so if you count from 0 to  you get 0.5 that is exactly the same that
 you get 0.5 that is exactly the same that  (for convention the left of the 0 is taken as negative and the right as positive).
 (for convention the left of the 0 is taken as negative and the right as positive).
 
        
             
        
        
        
The slope is 4/3. 
I hope this helps :)
        
             
        
        
        
Length is 95 yards.
The perimeter of a rectangle is the sum of four sides. The four sides are either its length or width. 
A rectangle has four sides where its angles are all right angles and its opposite sides are congruent or of equal size. 
Perimeter = 2length + 2width ==> P = 2L   + 2W
354 = 2L + 2(82)
354 = 2L + 164
to get the length. we must transfer all like signs.
2L = 354 - 164
2L = 190
2L / 2 = 190 / 2
L = 95 yards.
