Answer:
7.  7.8
Step-by-step explanation:
We can use Tan of this angle to find the missing side (in this case, the side adjacent to the angle measuring 57°)
  Tan A = (opposite side)/(adjacent side)
     Tan 57° = 12/x
solve for x
            x(Tan 57°) = 12
                x = 12/(Tan 57°)
                  x = 7.8   (rounded to the nearest tenth)

5/6(3/2) = 15/12

First you need to make both bases the same:
Lets remove the ^p and ^4
To make the base of 42 equal to 41, you would have 41^x = 41
 X - ln(42) / ln(41) = 1.00648904
Now you have 41^1.00648904(p) = 41^4
Now the bases are equal so we need to set the exponents to equal:
1.00648904(p) = 4
Divide both sides by 1.00648904 to solve for P
P = 4 / 1.00648904
P = 3.97421114
