Answer:

$\tt B)\;93^o$

Explanation:

$\tt 2(19x+1)+(19x+1)+15x=360$

$\tt 38x+2+19x-2+15x=360$

$\tt 38x+19x+15x+2-2=360$ (Add similar elements)

$\tt 72x+2-2=360$ (2-2=0)

$\tt 72x=360$

$\tt \cfrac{72x}{72}=\cfrac{360}{72}$ ( Divide both sides by 72)

$\tt x=5$

Now,

m∠km:-

$\tt 19x-2$

$\tt 19(5)-2$ (Multiply 19*5= 95)

$\tt =95-2$ (Subtract)

$\tt = 93$

Therefore, m∠km=93° is the answer.
