These angles are also known as vertical angles or opposite angles. So looking at the equation, I can see that there are currently terms on both sides of the equation, and I’d like to collect all the terms on the same side, the left-hand side. Solution: Let us assume that the smaller angle = x, then the larger angle = 2x, We have, `x + 2x = 180°`Or, `3x = 180°`Or, `x = 180° ÷ 3 = 60°`Hence, `2x = 120°`.
