Question

If a,b,c are the sides of a standard triangle A B C such that a=2,b=1 and c= 3,then the acute angle

∠B=……​

Answer 1

Answer:

angle b = 30°

Step-by-step explanation:

let us suppose a is 2x, b is x and c is 3x

a+b+c=180°

2x+x+3x=180°

6x=180°

x=180°/6

x=30°

angle b is x and x is 30°

therefore angle b is 30°

Answer 2

Such a triangle is not possible because sum of 2 sides must be greater than 3rd side and 1+2=3
