Answer 2

Explanation:

HERE,

angle A=x+5

angle B=3x

angle C=x

we know that,

sum of three angle of a triangle =180°

According to the question,

`\tt{ x+5+3x+x=180 }`

`\tt{5x+5=180 }`

`\tt{ 5x=180-5 }`

`\tt{5x=175 }`

`\tt{ x=(175)/(5) }`

`\tt{x=35 }`

So,

`\bold{\angle{B}=3x=3×35=105° }`
