Two straight lines intersect. One angle is $(x + 30)$ deg and the angle adjacent to it (forming a linear pair) is $(2 x)$ deg.
Find the value of the larger of these two angles.

Question

Two straight lines intersect. One angle is (x + 30) deg and the angle adjacent to it (forming a linear pair) is (2x) deg. Find the value of the larger of these two angles.

Accepted Answer

100. Linear pair: (x + 30) + 2x = 180, so 3x = 150 and x = 50. The angles are 80° and 100°; the larger is 100°.
