Answer:
x=7
Step-by-step explanation:
write -2+16x+9x+7=180
then add all like terms (-2+7=5) and (16x+9x=25x)
5+25x=180
-5. -5
25x=175
/25. /25
x=7
Answer:
15
Step-by-step explanation:
7-(-1) is 8
8 divided by 4 (x or “run” of slope) is two
Two times five (y/rise of slope) is ten
5 (from original point -1,5) plus 10 is 15
(7,15)

Hence, x = 0°, 180° and 360° <em><u>Ans</u></em>
