In a triangle, the first angle is 2 times larger than the second, and the third angle is 40 degrees larger than the second.

In a triangle, the first angle is 2 times larger than the second, and the third angle is 40 degrees larger than the second. What are the angles of a triangle?

x is the first corner.
2x is the second corner.
2x + 40 is the third corner.
180 is the sum of the angles in a triangle.
x + 2x + 2x + 40 = 180
x + 2x + 2x = 180-40
5x = 140
5 5
x = 28 is the first corner.
2 * 28 = 56 – the second corner.
56 + 40 = 96 is the third corner.
