The Triangle Angle Sum Theorem states that the sum of the angles in a triangle is always equal to 180 degrees.
In the given triangle, we know that angle D is 22 degrees and angle ABC is 103 degrees.
To find the measure of angle C, we can subtract the measures of angles D and ABC from 180 degrees:
180 degrees - 22 degrees - 103 degrees = 55 degrees
Therefore, the measure of angle C is 55 degrees.
Use the image to answer the question.
An illustration shows a triangle with vertices as B C D. Angle C on the top is labeled as a question mark and angle D on the bottom right is labeled as 22 degrees. Vertex B is on the bottom left. The horizontal line D B extends beyond the triangle to the left with an arrow at the end, and a point A is marked on it. The angle of A B C is labeled as 103 degrees.
Use the Triangle Angle Sum Theorem to find the measure of the angle on point C .
