The answer is B - 43.25

The two congruent sides will have congruent angles. One angle measurement is given. Triangle angles equal 180.

Take 180 and subtract the given angle 93.5. Then divide by 2 to get the measurements x and the other unknown.

180 - 93.5 = 86.5

86.5/2 = 43.25

Please help me answer this. My professor taught us this but with the formula on the right.

ASHA 777 [7]

First lets rearrange the formula to solve for half-life.
The half-life is the time it takes for half of the element to decay.
$e^{rt} = \frac{1}{2} \\ t = \frac{ln (\frac{1}{2})}{r}$

So now we need to find "r" which is the rate of decay.
If we rearrange formula to solve for r:
$P e^{rt} = A \\ \\ r = \frac{ln (\frac{A}{P})}{t}$

Substituting this into equation for half-life, you get:
$T = (\frac{ ln (1/2)}{ln (A/P)} ) t = \frac{ ln(1/2)}{ln (200/500)} *(48) = 36.31$
