Question

two adjacent angles of a parallelogram are in the ratio 4:5 find the measure of each of its angles

Answer 1

the sum of the adjacent angles is 180 so

4x + 5x =180

9x = 180

x =180/9 = 20

4x=20*4 = 80

5x=20*5 = 100

so the measure of each its angles is 80 100 80 100

HOPE THIS HELPS

PLS MARK AS BRAINLIEST

Answer 2

HLO MATE !!!!

HERE IS UR ANSWER _________________
_____________________________________

$Given \: that \: ratio \: of \: anjacent \: angles \: = 4 : 5 \\ \\ Let \: the \: angles \: be \: 4x \: and \: 5x \\ \\ As ,\: we \: know \: that \: sum \: of \: adjacent \: angles \: \\ in \: parallelogram = 180°\\ \\ Now, \: Acc.to \: statement : \\ = > 4x + 5x = 180 \\ = > 9x = 180 \\ = > x = 20$
4x = 4(20) = 80
5x= 5(20) = 100

So, The angles are 80° and 100 °....
