A radioactive substance decays at a rate of 10% per hour. which equation can you use to 5% of the substance left after 3 hours? A.) f(3)=3(0.90)10
B.) f(3)=10(0.90)3
C.) f(3)=100(0.10)3
D.) f(3)=100(0.90)3

This information would not help to prove the triangles are congruent through SSS. SSS= Side-Side-Side, and we only have one piece of information about sides. The other two are about angles. If we had three sides then it would work, but we don't. This information would help us prove triangles GHI and RST are congruent through ASA or AAS, but not SSS.
