Answer:
47.3
Step-by-step explanation:
as shown above ,this question can be solved using trigonometry and hence we get the perimeter to be 47.3
A^2 + 9 = 36 now solve subtract 9 from both sides to get a^2 = 27 then find the square root of 27 and that should be your answer so like 5.196 something
4w-7k=28
-7k+4w+-4w=28+-4w
-7k=-4w+28
-7k/-7=-4w+28/-7
k=4/7w-4
