Explain how to find which is greater: 1/4 of 12 or 1/3 of 12. plsss me

1/3

Step-by-step explanation:

1/4=3/12

1/3=4/12

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.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
