Answer:
B
I
Step-by-step explanation:
A triangle's angles must add up to 180
68+90+x=180
158+x=180
22=x
3 and 2 must add up to 180
70+x=180
angle 2= 110
angle 2 and angle 1 have to add up to 180 as well
110+x=180
andgle 1= 70
<h2>4500 x 6700-577=30149423</h2>
There is no positive or negative correlation
You need to add the sum in order to find the answer
Half-life = elapsed time * log(2) / log (bgng amt / ending amt)
half-life = (5 *

half-life = (5 *

<span>half-life = 1.505 / </span>
