Question

∠a and ∠b are supplementary. If m∠a = 2x + 1 and m∠b = 3x - 6, what is the measure of ∠b?                                         HELP PLEASE

Do you know what supplementary means? :)

Well, since you are not answering, I'll just tell you what it means.

If we have two angles let' say A and B and if they are supplementary then they must sum upto 180 degrees. [Also known as linear pair].

In your question you are given ∠a = 2x + 1 and ∠b = 3x - 6 are supplementary.

So     ∠a+∠b = 180

Now can you calculate it? :)

so the answer is ?

Try doing:

(2x + 1) + (3x - 6) = 180

I think it'd be better if you calculate that! Did you get the concept? Beacuse that is more important!

anonymous · Answer

In case you haven't gotten it yet:
(2x + 1) + (3x - 6) = 180
2x + 1 + 3x -6 = 180
5x + 5 = 180
5x = 175
x = ?
