D. 95 degrees
Explanation:
The sum of the angles in a triangle is always 180 degrees.
To find the measure of DBC, we can subtract the measures of angle ABC and ABD from 180 degrees.
DBC = 180 - 155 - 60
DBC = 180 - 215
DBC = 95 degrees
The measure of ABD is 60 degrees and the measure of ABC is 155 degrees. What is the measure of DBC?
A. 155 degrees
B. 215 degrees
C. 180 degrees
D. 95 degrees
