Supplementary angles add to 180 so x + 128.7 = 180 subtract 128.7 from both sides; therefore, the answer is 51.3

I hope this helps!

-25 = -4r + 5 please help
Andrej [43]
-25=-4r+5
Subtract 5 to each side
-25-5=-4r+5-5
-30=-4r
Divided -4 to each side
-30/-4=-4r/-4
7.5=r
Check:
-25=-4r+5
Substitute r with 7.5
-25=-4(7.5)+5
-25=-30+5
-25=-25. As a result, r=7.5. Hope it help!
