Quadrilateral Angless..?
The angles of a quadrilateral are 73 degrees, 2x degrees, 3x degrees and 102 degrees
Write down an equation in x.
I'd be more than grateful if you could help me. I have worked out what the angles is of 2x and 3x but I'm stuck on how to get an equation for it.
Can u please show me the method u use and how u got ur answer
Thanx :)

73 + 2x + 3x + 102 = 360
2x + 3x = 360 – 73 – 102
5x = 185
x = 185/5 = 37
2x = 2(37) = 74
3x = 3(37) = 111
The angles of the quadrilateral are {73º, 74º, 111º, 102º}
The sum of angles is 360 deg.
Then 73+2x+3x+102=360
5x=360-(73+102)=360-175=185
x=37
Then 2x=74
and 3x=111
Add them all together, they total 360 degrees
