Question

in a paralleogram A:B = 1:2 then A =​

Answer 1

Answer:

Value of A is 60°

Let ∠A be x and ∠B be 2x

As we know, that opposite angles are equal in a llgm

Hence

∠A=∠C and ∠B=∠D

and also ,

and also , sum of all angles = 360°

Hence,

= ∠A+∠B+∠C+∠D=360°

= 2(∠A+∠B)=360°

= (x+2x)=180°

= 3x=180°

= x=60°
