Question

Point D is an interior of ABC. what is m DBC can u help me pls

Answer 1

Answer:

36.5 degrees

Step-by-step explanation:

angle abc is a straight angle ( which is 180 degrees )therefore:

angle ABD + angle DBC = angle ABC

substituting the given measurements gives us=

3x + 22 + x - 4 = 180

4x = 162

x = 40.5

the question asks us to find measure of angle DBC so we substitute x which =

measure DBC = x - 4

measure DBC = 40.5 - 4

measure DBC = 36.5 degrees

hope this helps!! :)
