Answer:
B
Step-by-step explanation:
the sum of angles of triangle=180
B: 50+60+70=180
It's not commutative:
<em>a</em> * <em>b</em> = 3<em>a</em> + 2<em>b</em>
but
<em>b</em> * <em>a</em> = 3<em>b</em> + 2<em>a</em>
We have equality only for
3<em>a</em> + 2<em>b</em> = 3<em>b</em> + 2<em>a</em> → <em>a</em> = <em>b</em>
