PLEASE HELP ASAP I WILL MARK BRAINLIEST

so here is what you do write down your mulptication of 4 and 2 and then find out if they both have the same numbers on a couple or just one same number and then write that down and then make it a fraction

Step-by-step explanation:

tangent

step-by-step explanation:

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.
