ΔABC has the following angle measures: A = 40 degrees, B = 60 degrees, and C = 80 degrees. The triangle is reflected across the
x-axis to obtain ΔA’B’C’. What is the measure, in degrees, of angle B' ?
1 answer:
Answer:
60 degrees.
Step-by-step explanation:
A reflection does not alter the size of the angles of the triangle so B = 60 degrees.
