In a triangle, the two angles are 46 and 78 degrees, find its third angle.

Let’s find the degree measure of the third angle of the triangle:

As you know, the sum of the angles of a triangle is 180, so to find the degree measure of the third angle of a triangle, you need to subtract the sum of the two known angles of the triangle from the total sum of the angles of the triangle, we have

180 – (46 + 78) = 180 – 124 = 56.

Answer: The degree measure of the third corner of the triangle is 56.
