Answer: 17a) 32°
Step-by-step explanation:
Plot the coordinates and draw a line to connect them.
Then draw a horizontal line from (-4, 1) and a vertical line from (4, 6) until they intersect. This creates a 90° triangle.
Notice the length of the horizontal and vertical lines.
Use trigonometry to calculate the angle. Note that tan = opposite/adjacent
[tex]tan\ \theta=\dfrac{5}{8}\\\\.\quad \theta=tan^{-1}\bigg(\dfrac{5}{8}\bigg)\\\\.\quad \theta =32^o[/tex]
