Question

If m angle abc=80⁰ what is m angle dbc^ prime? Justify your reasoning.

Answer 1

In triangle ABC, if angle ABC is given as 80 degrees, angle DBC' is the supplementary angle and is equal to 100 degrees.

Step-by-step explanation:

In triangle ABC, if angle ABC is given as 80 degrees, we need to find angle DBC'.

Since angle ABC is 80 degrees, angle DBC' is the supplementary angle to angle ABC, which means it is equal to 180 degrees minus angle ABC.

Therefore, angle DBC' is equal to 100 degrees.
