two opposit angle of a parallelogtam are (3x-2) and (50-x) find the measure of each angle of parallogram
Answers
hey mate!
here is ur answer.
given, 2 opp. angles of paraleelogram are (3x-2) and (50-x).
We know that , opp.sides of parallelogram are parallel as well sd equal.
so...
3x-2=50-X
3x+x=50+2
4x=52
x=52/4
x=13.
so, angles of PARALLELOGRAM are 3x-2=37degrees
and 50-x=37degrees
the remaining two angles are 180-37=143degree.
: . , the angles are 37 , 143, 37 , 143 RESPECTIVELY.
hope it helps u mate!!!

Step-by-step explanation:
Let the //gm be ABCD .
Suppose given opposite angles are angleA and angleC.
Let angleA=(3x-2) and angleC=(50-x) .
Since angleA and angleB lie on the same side of AB ,
therefore angleA +angleB=180 degrees ,
that is (3x-2)+angleB=180
similarly angleC+angleD=180 degrees .
that is (50-x)+angleD=180
THEREFORE (3x-2)+angleB=(50-x)+angleD
that is angleB-angleD=(50-x)-(3x-2)=50-x-3x+2 =52-4x.
AGAIN angleA and angleD lie on the same side of AD
, therefore angleA+angleD=180degrees,
which means (3x-2)+angleD=180
ALSO angleB and angleC lie on the same side of BC therefore angleB+angleC=180degrees :
that is angleB+(50-x)=180
NOW (3x-2)+angleD=angleB+(50-x)
that is angleB-angleD=(3x-2)-(50-x)=3x-2-50+x =4x-52
THUS we have angleB-angleD=52-4x =4x-52 HENCE
52-4x=4x-52 that is 104=8x
OR 8x=104
OR x=104/8 =13 when x=13
THEN angleA=(3x-2)=39-2=37 degrees,
angleC=(50-x)=50-13=37degrees,
angleB=180-37=143degrees
,angleD=180-37=143degrees.
NOTE it is better to draw the diagram of//gm ABCD to understand the above solution,
