Which of the following is an equivalent form of the compound inequality -33 > -3X-62-36? 0-3-6-33 and 3X-62-36
03-62-33 and 3X-62-36
0-3x>-33 and -62-36
O-3-6-33 and 3X-65-36

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.

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
