That would be choice 2. One acute angle is the complement of the other
eg in a 90-60-30 triangle sine 30 = cos 60
The y-intercept is (0,7) and the x-intercept is (-2,0).
8 - 2x = -8x + 14 <em>subtract 8 from both sides</em>
-2x = -8x + 6 <em>add 8x to both sides</em>
6x = 6 <em>divide both sides by 6</em>
<h3>x = 1</h3>
It’ll be the one on the far right last one ;)
