Can anyone help me with this?

12.1

Step-by-step explanation:

41 + x = 90

x= 49

Sine rule:

Sin90 = Sin49

  16           y

y= 16sin49

y is approx. 12.1

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

i will u if u answer my question in math
