I've had the chance to be working out of a math textbook lately and I was hoping that someone could help me understand why I'm not agreeing with the "correct" answer for this question.
See the attached image for the question and diagram.
The answers provided in the back of the book are as follows:
9. a. (1) 41°
b. (1) 37° 30'
(2) 142° 30'
What I don't get is how angle 1 can be anything other than 36°. Is the picture somehow misleading me? Is there a mistake? This is driving me nuts.
.... Ok, and in the process of preparing everything to put on here, I figured it out. But I decided to leave it all here because it seems a waste to delete it all.
The second attachment is my screenshot trying to figure it out using SolidWorks. The picture in the textbook sure looks to me like they're giving a dimension for the angle formed by the intersecting lines. But the answers only make sense if you interpret this as the angle of the arc between the line endpoints on the circle.
Well, thanks for reading this.... it helped me to figure it out.
