Suppose ray BC bisects angle ABE and point D is in the interior of angle ABC. If the measure of angle CBD = 35 and the measure of angle ABE is 168, find the measure of angle DBE

Answer 1

make a reasonable sketch of the situation.
at 168°, angle ABE forms almost a straight line, draw it as such
It said that angle CBE bisects it, so angle CBE must be 84°, show it on your sketch

angle DBE = angle CBE + angle DBC
= 84 + 35
etc , all done
