Assuming that the angle is shown and the degrees is explicitly shown, then you can conclude the following:
If the angle >= 0 and the angle < 90, then the angle is an acute angle.
If the angle = 90, then the angle is a right angle.
If the angle > 90 and the angle <180, then the angle is an obtuse angle.
If the angle = 180, then the angle is a straight angle.
Look at the picture.
The equation:
10x - 15 = 6x + 9 <em>add 15 to both sides</em>
10x = 6x + 24 <em>subtract 6x from both sides</em>
4x = 24 <em>divide both sides by 4</em>
<h3>
x = 6</h3>
Well -7+17 would equal 10. Hope this helps!
