Answer:
511.425
Step-by-step explanation:
Easy add them all together = 2045.7 then divide by how many numbers are there so 4 thats 511.425 and theres ur answer please mark me as brainlest!
The number 36 is really 36.000000... with infinite zeroes
so to divide by tan move the decimal one place to the left
<span>so 36/ 10= 3.6 </span>
