Question

I need help with this problem. (See picture provided.)

Answer 1

1 will equal 64 you take 64 and subtract it by 180 that'll be 112..when the teacher ask you how you got 1 tell him/her that 1 and 3 are adjacent angles...if she ask how you got 4 tell him/her subtract 180-64= 112

Answer 2

<1 = 64 degrees
<1 and <4 make 180 degrees because a line is 180 degrees
so take 180 - 64 = 116
Therefore <4 is 116

To find x
take 180= 64+3x-25
141=3x
x=47
