plss help me answer this question ​

Answer 1

Answer:

60° , 120° , 60° and 120°

Step-by-step explanation:

ABCD is a parallelogram . So, the sum of adjacent angles is 180°.

<A + <D= 180°

x +2x = 180°

3x= 180°

x= 180°/3

x = 60°

now, all the interior angles are

<A= x= 60°

<B =2x=2×60°=120°

<C=x=60° and

<D =2x = 2×60° =120°
