Question 765306: Please help me solve this measurement.
I need to find the measure of angle DAB when B=85 degrees and C=33 degrees.
It is originally triangle ABC, but A is the mid-point of DC, making it DAB, as well. I know a triangle equals 180 so I added both degrees and subtracted it from 180 to give me angle A, which is 62.

You can put this solution on YOUR website!

I assume D is a point outside triangle ABC, and line CD (or DC) is an extension
of AC.

If so, then you can clearly see that angle DAB and angle A are supplementary
angles since DC is a straight line. That means that their sum is 180.

You have already calculated that angle A is 62 degrees which is correct.

So angle DAB = 180 - 62 = 118 degrees.

Hope you got it.
