Slope=-5
as the line goes 5 down and 1 right
The answer is B) 43<span>°
Angle ADB is an inscribed angle which means arc AB has an angle twice that of angle ADB. The angle of the arc would be the same as that of the central angle AOB. So, mAOB = 86</span>°. And since, mAOB = mBOC, then mBOC = 86° and arc BC has a measure of 86° as well. Angle BDC intercepts the arc BC which means half of the angle of arc BC is mBDC. So, mBDC = 43<span>°.</span>
I feel like there is something missing from this question, for example how large is the tree house? If these are just plain measurements, then I would opt for B.
I believe that your answer is correct
The answer is -7+19i because of the procedure used in math
