Step-by-step explanation:
The detailed step by step calculations are shown in the attachment.
So the given angles are supplementary (add to 180). You take the two and add them. 21x+5+37x+1. This gets set to equal 180. 58x+6=180. Subtract 6 from both then divide by 58. You get x=3

Subtract the numbers

Factor out 4 from the expression


When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -

- <em>Thus, Options A and F are correct!!~</em>
An inscribed angle (BAC) is one half the angle of a central angle (BOC) that intercepts the same arc. Therefore, BAC = 34 degrees.
