The angles of a triangle are 2: 3: 4. Find their degree measures.

Solution of the task:
1. Find what the sum of the numbers of the ratios of the angles of the triangle is equal to.
2 + 3 + 4 = 9.
2. Let’s find how many degrees fall on one part.
180/9 = 20 degrees.
3. Find what is equal to one corner of the triangle.
20 * 2 = 40 degrees.
4. Find out what the second angle of the triangle is.
20 * 3 = 60 degrees.
5. Find out what the third angle of the triangle is.
20 * 4 = 80 degrees.
Answer: One angle of a triangle is forty degrees, the second angle of a triangle is sixty degrees, and the third angle of a triangle is eighty degrees.
