assume that ABD has a measure of 105°

assign a variable and write an equation that will help you determine the measure of DBC

the measure of DBC is _____

Answer 1

you should know that a line is 180°

we can assign DBC the variable "x"

x = 180 minus the measure of angle ABD

so x = 180 - 105 which equals 75

the answer is 75°
