Answer:
<h3> 
           44</h3>
Step-by-step explanation:
z -  some integer
2z - first given even integer (the smaller one)
2z+2  - even integer consecutive to 2z  (the larger one)
2(2z)    - twice the smaller number
2(2z) - 40    - the number 40 less than twice the smaller number
2(2z) - 40 = 2z + 2
4z - 40 = 2z + 2
2z = 42
  
2z+2 = 42+2 = 44
check:
2(2z)-40 = 2(42)-40 = 84-40 = 44

Answer = d
using the 30 - 60 - 90 triangle theorem 
side across from the angle 
across from angle 30 is x 
across from angle 60 is x rad. 3
across from 90 is 2x 
BC is across from angle 60
so BC is the x rad 3
set the given measurement equal to it 
x sqrt 3 = 5
÷ sqrt 3 ÷ sqrt 3 
x = (5/ sqrt 3) 
multiply top and bottom by the radical to get rid of the radical in the bottom 
x = (5/ sqrt 3) × (sqrt 3/sqrt 3)
x = 5 sqrt 3/ 3 
since side BC is x
BC = 5 sqrt 3/ 3
