An investment is currently worth 1.2×107 dollars . twenty years ago, the investment was worth 9.6×105 dollars. how many times greater is the value of the investment today than the value of the investment twenty years ago? a. 0.125 b. 12.5 c. 125 d. 12,500

B.12.5, 1.2x10^7 is 12,000,000, and 9.6x10^5 is 960,000, 12,000,000 divided by 960,00 equals 12.5

ASA congruence theorem: If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

AAS congruence theorem: If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Consider two triangles ΔABC and ΔA'B'C' . If AB=A'B', m∠A=m∠A' and m∠B=m∠B', then two triangles ΔABC and ΔA'B'C' are congruent by ASA theorem. 
 Now find ∠C and ∠C': 
 and . 
You have AB=A'B', m∠A=m∠A' , m∠C=m∠C' and that is the condition of AAS congruence theorem. These thoughts show you that AAS theorem is straight extension of ASA theorem.
