Question

NEED HEEEELP! ∠a and ∠b are supplementary. If m∠a = 2x + 4 and m∠b = 4x - 10, what is the measure of ∠a?

Answer 1

a and b are supplementary means their sum is 180

since a = 2x + 4 and b = 4x - 10

then that means (2x + 4) + (4x - 10) = 180

do you get it?

Answer 2

No?

Answer 3

you cant subtract it its impossible to subtract something like that

Answer 4

or 6x-6 =180
6(x-1)=180
x-1 = 30
x = 31
