<em>by </em><em>angle </em><em>sum </em><em>property </em><em>of </em><em>triangle </em>
<em>let </em><em>the </em><em>angles </em><em>be </em><em>x </em>
<em>then,</em><em>, </em>
<em>x+</em><em>x</em><em>+</em><em>x</em><em>=</em><em>1</em><em>8</em><em>0</em>
<em>3x=</em><em>1</em><em>8</em><em>0</em>
<em>x=</em><em>6</em><em>0</em><em>°</em>
Answer:
Step-by-step explanation:
On your recent question- you stated that when the x value was 10, the y value was 2. The graph started at the origin. To find the constant of proportionality, use the equation . In this case, the "run" was 10, since it went +10 from 0. The "rise" was 2, since it went +2 from 0.
