Answer:
MKL = 36°
Step-by-step explanation:
(3x + 6) + (6x + 12) = 54°
3x + 6x + 6 + 12 = 54
9x + 18 = 54
9x = 54 - 18
9x = 36
x = 36/9
x = 4
MKL = 6x + 12 
MKL = 6(4) + 12
MKL = 24 + 12
MKL = 36°
 
        
             
        
        
        
Tanα=h/x
h=xtanα, we are told that x=6.5ft and α=74° so
h=6.5tan74 ft
h≈22.67 ft  (to nearest hundredth of a foot)
        
             
        
        
        
10⁻⁵  is the same number as  1 / 10⁵ .
        
             
        
        
        
100%-20%= 80%=0.8
115(0.8)= 92
92(1.075)= 98.9
The final price of the coffee table is $98.90. 
Hope this helps!
