Igoryamba

Answer:

<em>36:60:84</em>

<em>A     : B    : C</em>

<em>36° : 60° : 84°</em>

<em>A= 36°</em>

<em>B= 60°</em>

<em>C=84°</em>

Step-by-step explanation:

<em>3:5:7 =15</em>

<em>180÷15=12</em>

<em>3×12=36</em>

<em>36:x:y =180</em>

<em>5×12=60</em>

<em>36:60:y =180</em>

<em>7×12=84</em>

<em>36:60:84 =180</em>
