Mya created a model of a train switch to use in her model train set. The switched tracks are intersected by a third set of tracks, as shown in the diagram.

The measure of ZA is 78.6° and the measure of ZB is 15° less than the measure of
ZA. What is the measure of ZC to the tenth of a degree?

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

1) is right
