One corner of the triangle is 30 degrees larger than the other and 30 degrees less than the third corner.

One corner of the triangle is 30 degrees larger than the other and 30 degrees less than the third corner. find all the corners of this triangle.

1. Let’s say one corner of a triangle is x degrees.

2. The second will be (x – 30) degrees.

3. The third is (x + 30) degrees.

4. Using the solution of the equation, that is, finding the unknown, we determine the angles of the triangle.

x + x – 30 + x + 30 = 180;

3x = 180;

x = 180/3 = 60;

Answer: 1st x = 60 °; 2nd x – 30 = 60 – 30 = 30 °; 3rd x + 30 = 60 + 30 = 90 °.
