Question

all angle of a parallelogram is 20° less than its adjacent angle find the measure of all its angle

Answer 1

Hi Friend !!!

Here is ur answer !!!

Let the angle be a

other angle = a-20

a+a-20 = 180

2a = 180+20

a = 200/2

a = 100

other angle = a-20 = 100-20 = 80

So, angles are

80° , 100° , 80° , 100°


Hope it helps u : )

Answer 2

hiii. ....friend

the answer is here,

Let the angle be x. Then the adjacent angle will be x-20.

We know that ,

Sum of adjacent angles of a llgram is 180.

=> x+x-20 =180.

=>2x =200.

=> x=100.

So, The angles of the llgram are ,

100 , 100 , 80 ,80.
