To find the third angle of the triangle, we need to know that the sum of the angles in a triangle is always 180 degrees.
Given:
Angle A = 120 degrees
Angle B = 34 degrees
To find angle C:
180 - (120 + 34) = 180 - 154 = 26 degrees
Therefore, the measure of angle C is 26 degrees.
Question 1
A)
Use the image to answer the question.
An illustration shows a triangle with vertices as A B C. Angle A on top is 120 degrees and angle B on the left is 34 degrees. Vertex C is on the right.
Use the Triangle Angle Sum Theorem to find the measure of the third angle of the triangle shown.
