Answer:
ok so the value of x is 147°.
the only angle we know is 42, we know a full rotation is 360° so we can deduct that 42° + 2x+1 + -124+x = 360.
minus 42 from both sides and solve for x,
we get 3x = 441; x = 147.
1 - 2x < 11
-2x < 10
x < -5
Jack's mistake is that he was supposed to divide by -2 on both sides of the inequality, but he did not do that. By dividing by -2, he will get x < -5.
