Question

the sum of two opposite angle of a telegram is 140 find the the all angles of parallelogram​

Answer 1

Answer:

LET THE PARALLELOGRAM BE ABCD.

WE KNOW THAT OPPOSITE SIDES OF A PARALLELOGRAM ARE EQUAL.

IT IS GIVEN THAT THE SUM OF TWO ANGLES IS=140.

Step-by-step explanation:

SO, SINCE WE KNOW THAT THE SUM OF ALL ANGLES OF A PARALLELOGRAM IS 180. SO, WE SUBTRACT 180 FROM 140.

180-140=40

WE REQUIRE TWO MORE ANGLES WHICH IS EQUAL TO EACH OTHER. SO, WE DIVIDE 40/2

WE GET,

40/2=20

SO THE OTHER ANGLES ARE 20 DEGREES AND 20 DEGREES
