Question

in the parallelogram ABCD, angle A : angle B = 4 : 6 calculate angle A and angle B​

Answer 1

Answer:

the answer is 1/12

Step-by-step explanation:

Area of the Pallaeogram is - 1/2*d1*d2

1/2*4x*6x

1/2*24x

1/12=x

Answer 2

Answer:

Step-by-step explanation:

Let ∠B=x

∠A=3∠B=3x

AD∣∣BC

∠A+∠B=180  

o

 

3x+x=180  

o

 

⇒4x=180  

o

 

⇒x=45  

o

 

∠B=45  

o

 

∠A=3x=3×45=135  

o

 

And ∠B=∠D=45  

o

 

Opposite angles of parallelogram are equal

∠A=∠C=135  

o

 

Opposite sides of parallelogram are equal.

AB=CD

5x−7=3x+1

⇒5x−3x=1+7

⇒2x=8

⇒x=4

CD=3×4+1=13

Hence 135
