Answer 1

`\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.
