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

answer:

c 60% on edg

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
