Answer:
∠ 1 = 72°
Step-by-step explanation:
(4n - 2) and (2n + 17) are adjacent angles and sum to 180° , that is
4n - 2 + 2n + 17 = 180
6n + 15 = 180 ( subtract 15 from both sides )
6n = 165 ( divide both sides by 6 )
n = 27.5
Then
2n + 17 = 2(27.5) + 17 = 55 + 17 = 72
∠ 1 and 2n + 17 are vertical angles and congruent , so
∠ 1 = 72°
Answer:
15/2 or 7.5
Step-by-step explanation:
-4(x-1)+6x=2(17-x) PEDMAS
-4x+4+6x=34-2x combine terms
2x+4=34-2x subtract 4 and add 2x
4x=30 divide by 4
x=15/2
