Please help as soon as possible

Answer 1

Step-by-step 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,

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

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

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

$\tt{5x=175 }$

$\tt{ x=\dfrac{175}{5} }$

$\tt{x=35 }$

So,

$\bold{\angle{B}=3x=3×35=105° }$

Answer 2

The answer is D! good luck
