Ostrovityanka [42]

Answer:

$\displaystyle 25°\:and\:°65$

{105° = 2m∠1 - m∠2

_______________

$\displaystyle \frac{195°}{3} = \frac{3m∠1}{3} \\ \\ 65° = m∠1$

All you have left to do is this:

$\displaystyle 25° = -65° + 90°$

So, your two angle measures are $\displaystyle 25°\:and\:°65.$

After 3 days a sample of radon-222 has decayed to 58% of its original amount.(

iren2701 [21]

Half-life = [elapsed time * log (2)] / [log (begng amt / endg amt)]
half-life = (3 days * 0.30102999566) / log (1 / .58)
half-life = 0.903089987 / log ( 1.724137931)
half-life = 0.903089987 / 0.23657200643
half-life = 3.8174 days
