At a junction, three angles around a point on one side of a straight line are (x), (x + 30), (2x) and together they make the straight angle. Find the largest of these three angles.

Question

Accepted Answer

75. x + (x + 30) + 2x = 180, so 4x + 30 = 180, 4x = 150, x = 37.5. The angles are 37.5, 67.5 and 75. The largest is 2x = 75°.

At a junction, three angles around a point on one side of a straight line are $(x), (x + 30), (2 x)$ and together they make the straight angle. Find the largest of these three angles.
