find the value of x and state the angle relationship that you used to determine the value. pls help I am very confused​

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

Which is greater, 7 p 5 or 7 c 5? 7p5 7c5

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.
