Question

in a parallelogram ABCD angle A ratio Angle B is 2 ratio 3 then angle D is equals to dash​

Answer 1

Step-by-step explanation:

2:3= 2x+3x=5x=180 therefore x= 36,2x=72 &3x=108 and as B+D=180 (adjacent pair) ,D =180-108 hence we get D = 72 degree I hope it will help u

Answer 2

∠D=72°

Step-by-step explanation:

In a parallelogram,sum of adjacent angles is 180°.

In a parallelogram ABCD,

∠A:∠B=2:3

Let ∠A= 2x, ∠B= 3x

∠A+∠B = 180°

2x+3x = 180°

5x = 180°

x = 36°

If ∠A is opposite to ∠D,

∠A = 2×36°

    = 72°

⇒∠A=72°=∠D

⇒∠D = 72°
