which is the measure of ∠DBC?

Answer: 20°

Step-by-step explanation:

There is 180 degrees in the triangle.  ∠C is 50°,  ∠A is 80°,  ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.

Answer: 20 degrees

Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :

80 + 50 = 130

subtract that from 180 to find out what angle ABC is:

180 - 130 = 50

since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:

50 - 30 = 20

angle DBC = 20 degrees
