Tan 37,4 = opposite/adjacent
tan 37,4 = x/12,8
• then multiply both sides by 12,8
12,8tan 37,4 = x
Therefore x = 9, 79 x 100
= 97, 86
= 100
( I guess that’s how you can round it to the nearest hundred, please correct me if I’m wrong)

Time taken, t = 6:00 - 2:00 = 4 hour.
We know,
Therefore, the half-life of the isotope is 1.024 hours.
Hence, this is the required solution.
