So Hey! I’m new! And need help with this problem✨ Pre Aldabra is my weakness. Here’s the question! “Find the measure of the third angle of the following triangle,27.” I’m usually good at finding the third angle but it’s just one number. Answer pls.

i dont know sorry

step-by-step explanation:

the answer to this is a. a^2 + b^2 = c^2

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
