Two lines cross at a point. One angle is $(x + 35)$ ° and the angle adjacent to it (linear pair) is double the first angle.
Find $x$ .

Question

Two lines cross at a point. One angle is (x + 35)° and the angle adjacent to it (linear pair) is double the first angle. Find x.

Accepted Answer

25. First = (x + 35); adjacent = 2(x + 35). Sum = 180: (x + 35) + 2(x + 35) = 180, 3(x + 35) = 180, x + 35 = 60, x = 25.
