Using scientific notation, what is the solution to (5.75 * 104) / (2.5 * 103)?

2.3 * 102

23.0 * 101

2.3 * 107

2.3 * 101

step-by-step explanation:

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

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.

answer is 33
