In a triangle, the 2 angles are 46 and 78 degrees. Find its third corner.

By the condition of the problem in a triangle, 2 angles are equal to 46 and 78 degrees. We know that the sum of the degree measures in a triangle is 180 degrees. The first action is to find the sum of the degree measures of these angles. To do this, add the number 46 and the number 78 and get:
1) 46 + 78 = 124 degrees the sum of these two angles. The second action is to find the third corner. To do this, subtract the sum of these two angles from the sum of the degree measures of the three angles in the triangle.
2) 180 – 124 = 56 degrees third corner of the triangle.
Answer: 56 degrees.
