Final answer:
To find the unknown angle in a triangle, subtract the sum of the given angles from 180 degrees.
Step-by-step explanation:
To find the unknown angle in the triangle, we can use the fact that the sum of all angles in a triangle is 180 degrees. Let's denote the angles of the triangle as A, B, and C. If we know the values of angles A and B, we can find angle C by subtracting the sum of angles A and B from 180 degrees:
C = 180 - (A + B)
For example, if angle A is 45 degrees and angle B is 60 degrees, we would have:
C = 180 - (45 + 60) = 75 degrees.
