Lines l and m intersect so that the measure of ∠1 is 50°. What is the measure of ∠2?

Step-by-step explanation:

Without an illustration, I can’t know the position of ∠2 to ∠1.

If the angles are adjacent then ∠2 = 180° - ∠1 = 130°.

Otherwise, ∠2 = ∠1 = 50°

you need to add a picture

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
