Answer: The measure of the supplement of an angle of measure 0° is 180°
They are all (SAS)side angle side except for the bottom right one. This is because the question does not give the little ticks to show that one side is the same as the other. It is not good enough to assume they are congruent without proof.
Step-by-step explanation:
b + 81° = 117° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
b = 117° - 81°
b = 36°
for no. 14
The angles that are congruent to < 1 are < 4 and < 8.
