The sum of the angles is 360
We get an equation:
4x+124=360
x=236/4
x=59
Mila [183]3 years ago

x + 77 + 47 + 2x + x = 360

4x = 236

You answer: x = 59

59+77+59+47+59+59=360

Help... anyone????????
katovenus [111]
Since they both have 3x terms subtract the second from the first to get rid of the x terms...

  3x+2y=10
-3x+y=-13
__________
3y=-3

y=-1, which makes 3x+2y=10 become: 3x-2=10 so

x=4

So the solution is the point (4, -1)
