Question

Hindi figure find the four angles ABCD of the parallelogram ABCD​

Answer 1

Answer:

in BCD

summof all angle is 180°

so,

angle B + angle C+ angle D = 180°

2x + 3x+5x = 180°

10x = 180°

x = 180/10

= 18°

2x=18 * 2

= 36

3x = 3*18

= 54

5x = 5*18

= 90

Answer 2

Answer:

The given paralleogram is rectangle ,so each

angle is 90°.In the given figure rectangle is bisected into two triangles ABD triangle,BCD triangle.

Step-by-step explanation:

In triangle sum of three angles is 180°.

So In triangle BCD sum of three angles=180°

2x+5x+3x=180°

10x=180°

x=18

2x=36

3x=54

5x=90

Each angle in rectangle is 90°so

Angles in triangle ABD

Angle A=90°,B=90°-54=36,D=90°-36=54.

By this we conclude that angle A=90°,B=54+36=90°,C=90°,D=36+54=90°

By this we conclude that given paralleogram is rectangle....
