Question

In a parallelogram ∠A : ∠B = 1 : 2. Then find ∠A and ∠B. Please be fast

Answer 1

Answer:

Correct option is

B

60

∘

Let ∠A be x and ∠B be 2x

As we know, that opposite angles are equal in a parallelogram.

Hence,

∠A=∠C and ∠B=∠D

and also ,

sum of all angles = 360

∘

Hence,

∠A+∠B+∠C+∠D=360

∘

2(∠A+∠B)=360

∘

⇒(x+2x)=180

∘

⇒3x=180

∘

∴x=60
